# Do acid base reactions always produce salt?

Jun 30, 2016

Why yes, they does.

#### Explanation:

$\text{Acid + Base "rarr" Salt + Water}$

Examples include:

$H X \left(a q\right) + N a O H \left(a q\right) \rightarrow N a X \left(a q\right) + {H}_{2} O \left(l\right)$

$N {H}_{4} X \left(a q\right) + N a O H \left(a q\right) \rightarrow N a X \left(a q\right) + {H}_{2} O \left(l\right) + N {H}_{3} \left(l\right)$

${H}_{2} S {O}_{4} \left(a q\right) + N a O H \left(a q\right) \rightarrow N a H S {O}_{4} \left(a q\right) + {H}_{2} O \left(l\right)$

${H}_{2} S {O}_{4} \left(a q\right) + 2 N a O H \left(a q\right) \rightarrow N {a}_{2} S {O}_{4} \left(a q\right) + 2 {H}_{2} O \left(l\right)$

${H}_{3} P {O}_{4} \left(a q\right) + 2 N a O H \left(a q\right) \rightarrow N {a}_{2} H P {O}_{4} \left(a q\right) + 2 {H}_{2} O \left(l\right)$

$H C \equiv N \left(a q\right) + K O H \left(a q\right) \rightarrow K C \equiv N \left(a q\right) + {H}_{2} O \left(l\right)$

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 $N {H}_{3}$, would both cause some hydrolysis.
