Why is solvation(hydration) of anions easier than that of cations?

[mollyp]

What is the charge on an anion?

What are the two elements that make up water and their charges? 

Would an anion be more attracted to a charge that is the same or different than itself?

Then think about how hydration happens.  Is hydration a chemical or physical reaction?

See what you can figure out with that information.
