Expert Answer

Step 1

All known compounds can be dissolve in certain solvents whereas they remain insoluble in other solvents.

Step 2

Ionic compounds are soluble in polar solvents as “Like dissolves like.”  Therefore polar solvents like water acts as good solvent for ionic compounds.

Step 3

The solubility curve can be used to determine the solubility in water at different temperature. Some of solutes / compounds are more soluble in water whereas so...
