Question

What is the colour of sodium sulphate solution?

Answer 1

Sodium sulphate solution (Na2So4) is white.

Answer 2

The color of an aqueous solution of sodium sulphate is white.

Explanation:

Sodium sulphate or $Na_2SO_4$, is a crystalline salt of sodium formed by the reaction of sulphuric acid $(H_2SO_4)$ and sodium hydroxide (NaOH). It is a neutral salt i.e., it has a pH of 7.

When dissolved in water it forms a colourless to cloudy white solution i.e., precipitate. Hence the colour of an aqueous solution of sodium sulphate is white.
