   acids are substances that ionize in aqueous solutions to form hydrogen ions [H+ (aq)] and bases are substances that dissociate to form hydroxide ions [OH- (aq)] in aqueous solutions this theory has changed slightly due to new knowledge - the hydrogen ion actually hydrates to form hydrogen [H3O+ (aq)] - not all bases contain hydroxide

   Bases turn red litmus paper to blue. Bases may be corrosive. (NaOH) Bases are usually oxides or hydroxides of metals. Bases are usually insoluble in water. Bases that are soluble are called alkalis. Bases are electrolytes. Bases have pH above 7. Bases are proton acceptors. Bases are neutralized by acids.

   According to the Bronsted Lowry definition, some substances can act as acids or bases (are called amphoteric) For example: NH3 + H2O ---> NH4+ + OH-(base) (acid) Reverse Reaction: NH4+ + OH- ---> NH3 + H2O (acid) (Base) In this reaction the the base (NH3) in the forward reaction becomes an acid in the reverse reaction which is an example of a conjugate acid-base pair (two substances related to ...
