Question

is the compound soluble or insoluble in water? cas insoluble (s) soluble (aq)

Explanation:

Calcium sulfide (\(CaS\)) is generally considered insoluble in water. This is based on solubility rules in chemistry. Sulfides of most metals (except those of alkali metals and ammonium) are insoluble in water. Calcium is an alkaline - earth metal (not an alkali metal), so \(CaS\) follows the rule of being insoluble.

Answer:

insoluble (s)
