CHEM 130 Lecture 37: Acid-Base Concepts
Document Summary
Chem 130: general chemistry: macroscopic investigations and reaction principles - An acid is a substance that, when dissolved in water, increases the concentration of hydronium ion, h3o+ (aq) The h3o+ (aq) ion is referred to as h+ (aq) and is called a hydrogen ion. A base is a substance that, when dissolved in water, increases the concentration of hydroxide ion, oh- (aq) A substance that completely ionizes in an aqueous solution to give h3o+ (aq) and an anion. Hclo4(aq) + h2o(l) > h3o+ (aq) + clo4(aq) A substance that completely ionized in aqueous solution to give oh- (aq) and a cation. Naoh(s) -h2o-> na+ (aq) + oh- (aq) Hydroxides of group ia elements and group iia elements (except be) A substance that does not completely ionize in a solution. Exists in reversible reaction with the corresponding ions. All neutralizations involving strong acids and bases have the same h of -55. 90kj per mole of.
