Term | Definition |
---|---|
acid | produces ions h+ in a water solution |
base | forms hydroxide ions oh- in a water solution |
buffer | ions that react with added acids and minimize their effects on ph |
hydronium ion | acid dissolves in water interact with water h30+ |
indicator | changes color in acid and bases |
neutralization | chemical reaction |
ph | measures of the concentration of hydronium |
salt | negative ions from an acid combine with positive ions |
soap | organic salts with nonpolar, hydrocarbon ends that interact with oils and dirt and polar end that helps them dissolve in water |
strong acid | any acid that dissociates almost completely in solution |
strong base | any base that dissociates completely in 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 dissociates in solution |
weak base | does not dissociate completely in solution |
