The polarity of water enables it to serve as a solvent for polar substances.
A polar substance is a substance that has a positive end and a negative end. Water itself is a polar substance and this polarity enables it to dissolve polar substances.
For instance, HCl dissolves in water because it is polar. The positive end of the dipole in HCl attaches to the negative end of the dipole in water and the negative end of the dipole in HCl attaches to the positive end of the dipole in water.
This dipole - dipole interaction accounts for the dissolution of HCl in water.
Also, ion - dipole interaction accounts for the dissolution of ionic substances such as NaCl in water.
