Dear Pavitra,

When a solute is dissolved in a solvent, the attractive forces between solute and solvent particles must be great enough to overcome the attrcative forces (intermolecular forces)  within the pure solvent and within the pure solute. 
When solutes are dissolved, they become solvated if solvent molecules are sufficiently attracted to solute molecules or ions (usually by dipole or ion forces).
CaCO3 is insoluble in water because, it is stable in solid form.
Strong acids such as hydrochloric acid can dissolve CaCO3.
