The sodium sulphate does not contain multivalent cation however calcium sulphate contains so option (C) is incorrect. The calcium sulphate and calcium chloride both contain multivalent cation, so they cause hardness in water, so option (D) is correct. Therefore, option (D) calcium sulphate, calcium chloride, is correct.

The calcium sulfate then reacts with soda ash: Calcium sulfate + Soda Ash → Calcium carbonate + Sodium sulfate CaSO 4 + Na 2 CO 3 → CaCO 3 + Na 2 SO 4 . The calcium carbonate resulting from this reaction will settle out of the water. The sodium sulfate is not a hardness-causing compound, so it can remain in the water without causing problems.

When used, the sodium sulfate solution's specific gravity should be between 1.154 to 1.171 and the magnesium sulfate solution's specific gravity should be between 1.297 and 1.306. Either sodium sulfate or or magnesium sulfate can be used however, results from the two solutions will be significantly different.

Hardness The hardness of water is a measure of the amount of minerals, primarily calcium and magnesium, it contains.
