A solution/solute is said to be weak electrolyte if it partially ionizes or dissociates,meaning will have both it's ions and molecules in a solution.Weak electrolyte will ionize ranging from 1%-10%.

For a weak electrolyte the arrow points in both forward and backward directions as the solution has ions and molecules both.

$Strongelectrolyt{e}_{\left(aq\right)}<=>{{Cation}^{+}}_{\left(aq\right)}+{{Anion}^{-}}_{\left(aq\right)}+Molecules$

This is the general form of equation for a weak electrolyte.
