When an acidic solution is neutralised by a base, what determines the nature of the salt formed?
Answer and explanation
Correct answer: Strength of the acid and base
The governing concept is salt hydrolysis and the relative strengths of the reacting acid and base. A strong acid with a strong base generally gives a neutral salt, whereas a strong acid with a weak base tends to give an acidic salt, and a weak acid with a strong base tends to give a basic salt. Therefore the acid and base strengths determine the salt’s behaviour in water; container shape, colour, and zero temperature do not.
