Answer: Option (D) is the correct answer.
Explanation:
It is known that silver halides are insoluble in water. Hence, silver bromide which is yellow in color is also insoluble in water.
Solubility of calcium phosphate is [tex]1.08 \times 10^{-23}[/tex] which is very low. Hence, calcium phosphate is also insoluble in water.
Similarly, barium sulfate is a white crystalline solid also known as a precipitate and it is insoluble in nature.
When barium sulphide reacts with water then it leads to the formation of barium hydroxide and hydrogen sulphide. Barium sulphide is partially soluble in water.
The reaction equation for this reaction is as follows.
[tex]BaS + 2H_{2}O \rightarrow Ba(OH)_{2} + H_{2}S[/tex]
Thus, we can conclude that BaS compound will be soluble in water.
