My word...

Explanation:

Most alkali metal salts are soluble in aqueous solution. Sulfates TEND to be soluble (there are some exceptions that have to be LEARNED).

This site quotes an aqueous solubility of 140*g*L^-1 at standard temperature.

Yes.

Explanation:

If you consult a table of solubility rules, like the one below, you will see that sodium sulfate ("Na"_2"SO"_4") is soluble in water.

Yes, Na_2SO_4 is soluble in water.

Explanation:

To figure out whether a compound is soluble in water, refer to the following list of solubility rules. This set of rules is very important and should be memorized.

Higher number rules supersede. Na_2SO_4 contains Na^+ ions, and alkali metal ions are soluble, according to rule no. 2. So, we know that sodium sulfate is soluble.
