|---|---|
 acid | substance that produces hydrogen ions, H+, in a water solution |
| base | any substance that forms hydroxide ions, OH-, in a water solution. |
| buffer | solution containing ions that react with added acids or bases and minimize their effects on pH |
| hydronium ion | H30+ ions, which form when an acid dissolves in water and H+ ions interact with water |
| indicator | organic compound that changes color in acids and bases |
| neutralization | chemical reaction that occurs when the H30+ ions from an acid react with theOH- ions from a base to produce water molecules |
| pH | a measure of concentration of hydronium ions in a solution using a scale ranging from 0-14, with 0 being the most acidic and 14 being the most basic |
| salt | compound formed when negative ions from an acid combine with positive ions from a base |
| soap | organic salts with nonpolar, hydrocarbon ends that interact with oils and dirt and polar ends that helps them dissolve in water |
| strong acid | any acid that ionizes almost completely in a solution |
| strong base | any base that ionizes completely in a solution |
| titration | process in which a solution of known concentration is used to determine the concentration of another solution |
| weak acid | any acid that only partly ionizes in a solution |
| weak base | any base that does not ionize completely in a solution |
