Ferrous metals contain iron Non-ferrous metals do NOT contain iron
The mass of water does not increase when copper sulfate is added to the water, unless the copper sulfate is hydrated. The mass of the mixture of water and copper sulfate, of course, does increase.
Yes. Sodium sulfate is soluble in water.
Copper sulfate is not black. Combined with water, as hydrated copper sulfate, it is blue. Without water, as anhydrous copper sulfate, it is white.
Iron sulfate dissolves in water to make an aqueous solution of iron sulfate.
Hydrogen and Oxygen

No, all the sulfate compounds are highly soluble in water.
A water solution of iron sulfate is obtained.
Sodium sulfate dissolves when mixed with water.
Copper sulfate is soluble in water but doesn't react with water.
Evaporation, Condensation, Precipitation
Why does copper sulfate change its colour when water is added
