SODIUM SULPHATE :

FORMULA : NA2SO4

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

COLOUR :

WHITE

NOTE : IT IS IN THE CRYSTAL FORM .....

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

NATURE :

IT IS THE NEUTRAL SALT

MEANS ITS HYDROUS SOLUTION GIVES A PH. OF 7

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

IT IS SOLUBLE IN WATER

NON - SOLUBLE IN ETHANOL

Answer 2

If you add aqueous barium chloride BaCl2 solution and aqueous sodium sulphate Na2SO4 solution, a precipitate of barium sulphate is formed. The colour of barium sulphate, like all Group 1 and Group 2 metal salts, is white as a solid or precipitate, and colourless when dissolved in water
