Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are

everyone associates with acids and bases is the litmus paper‚ which has the ability to change the color in response to an acid or a base. Phenolphthalein is another common indicator use by beginners in chemistry because its color change is very obvious‚ making it easy to use. There are many other indicators that change color at different pH levels‚ and so are useful for different purposes. Many pigments found in nature can be quite effectively used as acid-base indicators. The purple eggplant peel

Acid-Base Titrations 6-3: Concepts in Acid-Base Titrations Titrations provide a method of quantitatively measuring the concentration of an unknown solution. In an acid-base titration‚ this is done by delivering a titrant of known concentration into an analyte of known volume. (The concentration of an unknown titrant can also be determined by titration with an analyte of known concentration and volume.) Titration curves (graphs of volume vs. pH) have characteristic shapes. The graph can be used

concept of a conjugate acid-base pair. Using equilibrium law and K‚ explain the relationship between the strength of an acid/base and its conjugate. Conjugate Acid-Base Pair: Conjugate acids and bases were presented by Bronsted-Lowry‚ who was a chemist who proposed the theory that both acids and bases required the transfer of a proton in order for there to be a reaction. An acid will donate a proton (proton donor)‚ forming what is considered to be a conjugate base. When the base accepts a proton (proton
