Question

Is `"Na"_2"SO"_4"` soluble in water?

Answer 1

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.

Answer 2

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.

Answer 3

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.
