Which one of the following is the most important characteristic of water to act as a good solvent?

a) Purity of water
b) Ionizing power of water
c) Polar nature of water
d) Dissolving power of water

Ans- c

Explanation-  This is because of polar nature of water molecule. Water molecule has uneven distribution of electron density. Water has a partial negative charge near the oxygen atom due the unshared pairs of electrons, and partial positive charge on hydrogen atoms. This makes it polar and it is able to act as a good solvent
