# What evidence indicates that a base dissociates in water?

Apr 11, 2018

We know a base dissociates in water if the solution is able to conduct electricity.

#### Explanation:

When bases dissociate in water, two ions are formed.
For example, when $N a O H$ dissociates in water, it separates into the $N {a}^{+}$ cation and the $O {H}^{-}$ anion.

These ions are both charged and able to move in solution. So, because it is a charge carrier, it will be able to conduct electricity.

This means that we can test whether a base dissociates in water or not by running an electric current through it.
