An ionic compound dissociates into its constituent ions upon dissolution in water. When Ca(NO3)2 is dissolved in water, the following reaction would occur.

Ca(NO3)2 ---> Ca2+ + 2NO3-

One mole of Ca(NO3)2 dissociates into one mole calcium ion and two moles of nitrate ion.

It dissociates into its ions Ca^2+ and (NO3)^-1. Ca(NO3)2 is an ionic substance and when dissolved in aqueous solution it will separate into its ions.
