The oxygen-sulfur bonds in sulfate are covalent...........

Explanation:

We could write a Lewis representation of SO_4^(2-) as (O=)_2S(-O)_2^(2-), or of the "parent acid" as (O=)_2S(-OH)_2. This is a bit old-fashioned, and some representations give stackrel(2+)S(-O^(-))_4, but it is still SO_4^(2-).

And typical sulfate salts are Na_2SO_4, CaSO_4, FeSO_4, and BaSO_4.
