Question

Do acid base reactions always produce salt?

Answer 1

Why yes, they does.

Explanation:

`"Acid + Base "rarr" Salt + Water"`

Examples include:

`HX(aq) + NaOH(aq) rarr NaX(aq) + H_2O(l)`

`NH_4X(aq) + NaOH(aq) rarr NaX(aq) + H_2O(l) +NH_3(l)`

`H_2SO_4(aq) + NaOH(aq)rarr NaHSO_4(aq) + H_2O(l)`

`H_2SO_4(aq) + 2NaOH(aq)rarr Na_2SO_4(aq) + 2H_2O(l)`

`H_3PO_4(aq) + 2NaOH(aq) rarr Na_2HPO_4(aq) + 2H_2O(l)`

`HC-=N(aq) + KOH(aq) rarrKC-=N(aq) + H_2O(l)`

Since I have deployed a strong base in each case, the reaction would lie strongly to the right. Weaker acids/weaker bases would give equilibrium mixtures. Mind you, `""^(-)C-=N` and `NH_3`, would both cause some hydrolysis.
