Document Summary

Hydronium ion: h+ ions react with h2o to create h3o, h+ ions are protons. The reaction: ha (aq) + h2o (l) a- (aq) + h3o+ (aq) The larger the constant, the stronger the acid. Ka = ([acid-] x [h3o+]) / [hacid] For the reaction: a- (aq) + h3o+ (aq) ha (aq) + h2o (l) Kw (ion-product constant): at a specific temperature, this is the product of the concentrations of. [h+] = [oh-] then, the solution is neutral. [h+] > [oh-] then, the solution is acidic. [h+] < [oh-] then, the solution is basic. Amphoteric substances: can act as an acid or as a base pk how the strength of an acid or base is expressed. Kb = 10-pkb stronger acid = smaller pka stronger base = smaller pkb. Finding the ph of a weak acid or base. The autoionization of water doesn"t affect its ph.
