Question

For the set of ionic compounds, CaSO4, CaCO3, Ca(OH)2, choose the correct characterization of their solubilities in water from the response list. Group of answer choices None of the three salts are soluble. All three salts are soluble. Two of the three salts are soluble. One of the three salts is soluble.

Answer 1

None of the three salts are soluble.

Step-by-step explanation:

According to the solubility rule, the carbonates and sulphates of group two elements are insoluble in water.

All three substances mentioned possess very low solubility in water and can be said to be slightly soluble in water. If we compare them with other ionic substances that dissolve readily in water, we can rightly say that they are insoluble in water.

Hence all three substances are insoluble in water.
