... When an acid and a base react, the products are a new acid and a new base. For example, the acetate ion, CH3COO–, in reaction 6.7 is a base that can accept a proton from the acidic ammonium ion, NH +4 , forming acetic acid and ammonia. We call the acetate ion the conjugate base of acetic acid, and w ...
