Explanation:
When an ionic compound dissolves in the water, the following happens :
-- the solvent solute attractive forces tries to overcome the solute solute attractions.
-- the water dipoles' negative end attracts the positive ions
-- the water dipoles' positive end attracts the negative ions
For example,
NaCl which is an ionic compound and also a strong electrolyte, it dissociates into water on the hydrated Na cations as well as Cl anions.
In water, the oxygen has negative charge and thus attracts the positive ions of the sodium, whereas the hydrogen is of positive and it attract the ions of chlorine which is negative.
