# Question #62207

A neutralization reaction is when an acid and base react to form salt and water.

Here are a few examples, I like to use HOH for water because it helps to illustrate that these reactions are double replacement.

HCl + NaOH -> NaCl + HOH

2HF + $C a {\left(O H\right)}_{2}$ -> $C a {F}_{2}$ + 2HOH

A neutralization reaction is very much like a double replacement reaction, however, in a neutralization reaction the reactants are always an acid and a base and the products are always a salt and water.

The basic reaction for a double replacement react takes the following format:

$A B + C D \to C B + A D$

we will look at an example as Sulfuric Acid and Potassium Hydroxide neutralize each other in the following reaction:

${H}_{2} S {O}_{4} + 2 K O H \to {K}_{2} S {O}_{4} + 2 {H}_{2} O$

In a neutralization reaction between an acid and a base the typical outcome is a salt formed by the positive ion from the base and the negative ion from the acid. In this case the positive potassium ion (${K}^{+}$) and the polyatomic sulfate ($S {O}_{4}$) to for m the salt ${K}_{2} S {O}_{4}$.

The positive hydrogen (${H}^{+}$) from the acid and the negative hydroxide ion ($O {H}^{-}$) from the base form the water $H O H$ or ${H}_{2} O$.

I hope this was helpful.
