When weak acids and bases react, the relative strength of the conjugated acid- base pair in the salt determines the ph of its solutions the salt, or its solution, so formed can be acidic, neutral or basic a salt formed between a strong acid and a weak base is an acid salt, for example nh4cl a salt formed between a weak acid. The reaction of an acid with a base to produce only salt and water is called a neutralization reaction acids acids are sour in taste if hydronium ions are found in a solution, the solution is acidic in nature hydronium ions are the only positively-charged ions (cations) formed when an acid dissolves in water all the properties.
