Why do polar substances such as sodium chloride dissolve so

Why do polar substances such as sodium chloride dissolve so readily in water? The sodium ions repel the partial negative end of the water dipole. Sodium chloride is a very dry powder, and the water is able to soak into the salt. Spheres of hydration form around the sodium and chloride ions None of the above All of the above.

Solution

None of the above

Sodium is positively charge and chloride is negatively charged. Similarly water H2O has positively charged and Negatively charged.

The negatively charged chloride is attracted to positively charged part of water. So water cannot be repealed it is attracted to each other because of which (salt) sodium Chloride will dissolve in water easily.
