Do acid base reactions always produce salt?

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.
