Respuesta :

Based on the solubility rules for the given set of compounds

All lead salts (Pb2+), carbonates (CO3^2-), oxides (O^2-) and sulfides (S^2-) are insoluble in water, whereas all chlorides (Cl-) salts are soluble in water.

A) ZnS - Insoluble

B) Au2(CO3)3 - Insoluble

C) PbCl2 - Soluble

D) MnO2 - Insoluble

Ans) A ) PbCl2

Answer:

All the given substances are insoluble in water

Explanation:

According to solubility rule-

(1) All sulfides are insoluble except alkali and alkaline earth metals.

So, ZnS is insoluble in water.

(2) All carbonates are insoluble except [tex]NH_{4}^{+}[/tex] and alkali metals.

So, [tex]Au_{2}(CO_{3})_{3}[/tex] is insoluble in water.

(3) All chlorides are soluble except AgCl, [tex]Hg_{2}Cl_{2}[/tex] and [tex]PbCl_{2}[/tex]

So, [tex]PbCl_{2}[/tex] is insoluble in water.

(4) All metallic oxides are insoluble except [tex]NH_{4}^{+}[/tex] and alkali metals.

So, [tex]MnO_{2}[/tex] is insoluble in water.
