| A | B |
| acid | A polar covalent substance that produces hydrogen ions in solutions |
| base | An ionic substance that produces hydroxide ions in solutions |
| indicator | organic compound that changes color in an acid or base solution |
| litmus paper | paper which has an indicator soaked into it |
| pickling | a process that removes impurities, such as oxides, from the surface of metals |
| hydronium ion | the ion that makes a solution acidic; formed when a the positive hydrogen ion from an acid forms a weak bond with the negative end of the polar water molecule |
| conductivity | ease of ionization/dissociation |
| strong acid | an acid that ionizes almost completely in solutions |
| strong base | a base that dissociates almost completely in solutions |
| weak acid | an acid that only partially ionizes in solution |
| weak base | a base that only partially dissociates in solution |
| pH | a measure of the hydronium ion concentration; relates to strength |
| neutralization | a chemical reaction between an acid and a base which produces water and a salt |
| salt | a compound formed between the negative ion from an acid and the positive ion from a base |
| titration | a measure of the concentration of an acid/base |
| endpoint | the exact moment when a color change occurs during titration |
| ph meter | a tool that precisely measures the pH of a substance |
| acid rain | any form of precipitation (rain, fog, snow) that has a pH less than 5.6 |
| ionization | process where a polar covalent compound, such as an acid, dissolves to form ions |
| dissociation | process where an ionic compound, such as a base, dissolves to form ions |
