but all the different classes of compounds that exist there are two acids and bases that are fundamental to the functioning of our world they are essential life  stay with the heart of a host of processes of Nature and they are important in many Industrial Products and processes we are going to examine the properties of that information illustrate how these compounds influence our world massad's the very word evokes your Dreadful rolls of corrosive liquids to eat away at almost everything and yes there are many different types of I come like ascorbic acid better known as Vitamin C are essential for life  when they are dissolved in water acids make solutions that taste sour foods that contain acid include citrus fruits cheese and sour milk  chode is also a mild acid bases have a bitter taste soap including materials are bases and anyone was accidentally put can a test of the bitter taste to the touch acids feel like water but he didn't orange when you have a sore in your mouth you will find out that even mild rashes can sting Jason's on the other hand feel slippery like soapy water both acids and bases are you up to write good conductors of electric current  acids react vigorously with Metals touch iron aluminum and magnesium this is a piece of magnesium and hydrochloric acid the reaction produces hydrogen this is on the other hand do not react with metals tennis can use these and other tests to determine is oceans or bases like a much easier and accurate test is a pH indicator paper the special paper reacts with awesome face turns indicator paper blue an acid turn litmus indicator inexpensive type of solutions the 17th century English chemist Robert Boyle was the first to study acids and bases in a systematic way  whale sounds these two types of compounds counteract each other react with bases so that the properties of both are lost to form water and stop this process is called neutralization  Boyle's observations were an important but he could not why do fractions work it was not until the late 19th century the spontaneous made of starts to unravel this mystery Arena Stone the water often to dissolve both acids and bases by separating them into individual free sample hydrochloric acid HCL separates in water what is happening in this reaction reset the original molecule made up of one atom of hydrogen and one atom of chlorine dissociates in water into its constituent ACL -  the hydrogen has become a positively charged ion or cation while the chlorine has become a negatively charged ion or anion hydrogen has only one proton and one electron so a positive hydrogen ion is one simple proton Iranians found a similar process works when bases are dissolved in water but rather leasing a positive hydrogen ion it generates hydroxide ions oh mice NaOH is dissolved in water is a reaction in water the sodium hydroxide dissociate show me how a becomes a positive ion because it's electron has gone to hydroxide oh - which is a negative ion Arrhenius surrounding by defining acids are substances that release hydrogen ions H+ when dissolved in water and bases are substances of generate hydroxide ions when dissolved in water this definition of sprained a number of things it showed a passage of similar properties and bases have similar properties as to why neutralize each other when is two substances are mixed together the H+ from the oh the base to produce H2O water  Arrhenius was also able to show her in the neutralization process an acid and a base are combined they produce water and a salt the general equation or acid plus base reduces water Plus Salt for example when hydrochloric acid is combined with sodium hydroxide a base Place water in an ionic compound called a salt we think of salted table salt that we put on food but there are many different salts ionic compound Venus's explanation of acids and bases for the important but there were problems with it his definition could not explain number of products like baking soda acted like a base but did not have any hydroxide ions explanation also referred to the actions of acids and bases in water  in 1923 a Danish chemist Johann bromstad and an English chemist the story published but similar findings that we find arrange his work for their theories I've come to be called to bronsted and Lowry definition of acids and bases the definition that are used for acid with similar to Arrhenius an tradition with a substance that can donate a hydrogen ion or proton but their definition of a base is very different made of any substance that can accept a proton essentially a base is the opposite of an acid  the Bronx Glory definition expands the number of substances that can be arms and bases relationship Victory octane oil can act like bases under the Bronsted-Lowry definition of acids and bases are related to the concentration of hydrogen ions or protons increase the concentration Libations decrease the concentration by accepting there for the acidity or basicity of something can be measured by proton patient summer vinegar are relatively mild if you still a little on your hand when you put it on a salad not much to worry about it but others like hydrochloride HCL are very strong and can be extremely dangerous  as the two solutions sitting beakers they look virtually the same but why is one so much stronger than the other  a strong acid is one that readily transfers H+ ions to the more complete the transfer of hydrogen ions the stronger the acid for example when hydrochloric acid is mixed with water nearly all of the HCL molecule transfer the H+ ions to water to you iron four-page 305 by contrast a weak acid like vinegar does not dissociate or transfer H+ ions as readily in water only 0.4% of the acid molecules and vinegar transfer their H+ online that 99.6% does associate that is why there is such a weak acid and why hydrochloric acid is so strong Truck Centers that have the strongest attraction for H+ ions are strong bases wine30 to make the mortar that holds bricks together is a very strong base the oxide ion 02 - that is found in the line strong atraxi H+ ion  I'll be base compounds only partially reacts with water these are weak finger water has the tendency to equalize the strength of all strong acids and strong bases are dissolved in water they lose their H+ ion to the water and 3:05 this morning which is a weaker acid than the original the same way when strong bases are dissolved in water they gain H+ ion from the water and become weaker as the leveling effect also acids and bases react very differently they are connected in similar chemical reactions according to the Bronsted-Lowry definition an acid is a proton donor and a base is a proton acceptor when an acid donates a proton to Romaine Park in shut up protein so what is now a base this is called a conjugate acid-base pair and they differ by only one proton this chart shows shuttle conjugate acid base pairs there is an inverse relationship between the strength conjugate base and it's time to get the stronger the acid the weakest conjugate base and the stronger the base So Weezer is trying to get this relationship rules of solution can sometimes be change from acidic to basic and Back Again tristick important for all living things can act as either an acid or a base when a water molecule gives up an H+ ion to become an o h - iron it is a accessories for Scion to become an HBO it is a base  this chest occurs naturally even in the purest of water but only in fractions of amounts with pure water the amount of h3o + is 10 to the - 7 multimeter for 110 millions of them all the leader  Adobe Zara cutaway small amount they are measurable and determine whether a solution is an acid or a base  the 1909 attorneys biochemist Shawn Sorensen proposed a way of measuring the concentration of h3o + firearms in solution and is a measure the city and basically it is known as the potential hydrogen or pH scale this is the p some common Solutions and products I would sit above the pH scale is in the center and the measure of h3o + is shown below the pH scale is a measurement of the amount of h3o + ions in the solution is reminder 7 more the others range from 10 to the -1 to 10 to the - 14 the pH number, from the opponent notice for water with a pH of 7 is right in the middle of the scale all of the solutions were lower than Saturn our asses all those higher than 7 are bases lemon juice free gravel is an awesome it has a measure of a boat to the mind 2.530 + ions in solution on a pH scale measures 2.5  bleach is a strong base and measures 12.5 on the pH scale it has about ten to the minus 12.53 give me solution  at first glance the pH scale seems complicated but it is really an ingenious measurement of the acidity basicity of compound and a very useful chemistry tool the acidity and basicity of compounds is at the heart of Tennessee and many people from Farmers to Medical must know about the impact of pH levels if they are going to be effective in their work many substances acids or bases react with other substances all of the time  plant generally prefer neutral soil with ph ranging from 6 to 8 but each species is a little different roses people prefer slightly acidic soil of between pH 5.8 and 6 two  series formula gardeners Intercity having emoji colors in blossoms in their Gardens carefully monitor the pH of their flower bed  Experience Project know the pH of the is very important that they are to maximize yield and they adjust pH by adding fertilizer  rainforest Marjorie Fritz pH water is between 6 and 7 on the pH scale but rain with a pH of below 5.6 is called acid rain some rainfall has been measured as low as pH 3.5 the cause of acid rain is coal-burning power plants and the exhaust from automobiles the burning of fossil fuels releases sulfur dioxide and sulfur trioxide which combines with water to produce acid  acid rain harms both living and nonliving things it can Corolla marble and limestone  plants can be seriously damaged by acid rain it washes the nutrients out of the soil manages the weeds and bark of trees and harms the root systems of plants  the rainfall and kills fish and other Aquatic Life  the balance of acids and bases in the bodies of animal is vital to their survival the pH in different parts of a human body varies considerably saliva is slightly acidic while there are strong from the stomach and intestine the play an important role in the digestion process  the PH of blood is particularly German blood must have a pH between the narrow range of 7.35 and 7.45 anything outside can lead to serious health problem our bodies have a special method to keep the pH at a normal level Ashley from bases called buffers in her bloodstream which released or absorbed H+ ions to keep a normal pH bases and acids are fundamental to life itself both acids and bases are electrolytes good conductors of electric current true or false  basis please react with Metals true or false  message react with bases so that the properties of both are lost to form and assault this is called  irenaeus defined acids are substances that generate Scion 08 -
