# How do conservation of mass and conservation of charge apply in an acid-base reaction....?

Oct 3, 2016

Mass and charge are conserved in every chemical reaction, so.........

#### Explanation:

So if a proton, ${H}^{+}$, is added, the mass and charge will increase by one unit each.

We can demonstrate this by looking at water's autoprotolysis reaction:

$2 {H}_{2} O r i g h t \le f t h a r p \infty n s {H}_{3} {O}^{+} + H {O}^{-}$

One water molecule receives a proton, and the donor formally loses a proton. Are mass and charge conserved here? If not they should be.
