An aqueous solution of CaCl2 is a neutral solution. Calcium chloride (CaCl2) is a salt composed of a cation, calcium (Ca2+), and an anion, chloride (Cl-). When dissolved in water, the ions dissociate and become surrounded by water molecules. The dissociation of CaCl2 does not result in the formation of any H+ or OH- ions, so the solution does not have any excess of either acid or base. Hence, the solution remains neutral.
