# Which is more conductive?

There are two choices. One is Nitric acid, and the other is phosphoric acid.

The solution of each type of these acids has a concentration of 0.1 mole. I answer would be phosphoric acid, because each molecule contains more than 1 hydrogen ion. Thus it would be more conductive.

Does strong/ weak affect conductivity?

Whether the acid is a strong or weak acid does affect its conductivity. Weaker acids are less dissociated and generate fewer ions in the equilibrium.

Nitric acid $\ce{K_{a}=24}$

Phosphoric acid $\ce{K_{a}=7.1 x 10^{-3}}$

Nitric acid is more dissociated than phosphoric acid
