B)Cu(OH)₂
C)LiCl
D)CaSO₄
E)PbCO₃

LiCl is an ionic compound consisting of a metal (Li) and a halogen (Cl). Ionic compounds typically dissolve in water because water is a polar solvent, and it can break apart the ions in the crystal lattice of the ionic solid through the process of hydration. Therefore, LiCl will be soluble in water.

AgCl is also an ionic compound, but it is insoluble in water because the Ag⁺ and Cl⁻ ions are strongly attracted to each other and the water molecules are not strong enough to break these bonds.

Cu(OH)₂ is a sparingly soluble compound which means it does dissolve in water to a small extent, but not enough to give a clear solution.

CaSO₄ is an ionic compound, but it is insoluble in water because the lattice energy (the energy required to break the ionic bonds) is very high.

PbCO₃ is an insoluble compound since it is an ionic compound and also has a low solubility product.
