The hexaaquachromium(III) complex ion is a weak Brønsted acid and will donate a proton to water. This process is called "hydrolysis" or an "acidity reaction". The reaction has an equilibrium which lies to the left.

Addition of aqueous acid will move the equilibrium to the left, and aqueous alkali will move to to the right.
