# How do you do acid base neutralization reactions?

Feb 8, 2014

An acid and and base neutralization involves an aqueous acid solution and an aqueous base solution combining in a double replacement reaction to form a salt and water.

Nitric acid plus calcium hydroxide yield calcium nitrate and water

$2 H N {O}_{3}$ + $C a {\left(O H\right)}_{2}$ -------> $C a {\left(N {O}_{3}\right)}_{2}$ + $2 {H}_{2} O$

$H N {O}_{3}$ has a leading hydrogen, usually a tip off that this is an acid
$C a {\left(O H\right)}_{2}$ has a trailing hydroxide usually a tip off that this is a base

The positive ion $C {a}^{+} 2$ from the base joins the negative ion $N {O}_{3}$ from the acid to form the salt. $C a {\left(N {O}_{3}\right)}_{2}$

The ${H}^{+}$ from the acid joins the $O {H}^{-}$ from the base to form water ${H}_{2} O$

Always in a neutralization reaction the products are two neutral substance salt and water.
