Question

Colour of Aluminium Sulphate when it is added to water

Answer 1

Aluminium sulphate is White in colour.
But, when water is added to Aluminium sulphate its colour(solution ) become colour less.

Answer 2

Aluminium sulfate is a solid white coloured chemical compound.The chemical formula of the aluminium sulfate is Al₂(SO₄)₃.

This chemical compound is highly reactive with the water,it produces aluminium hydroxide while reacting with the water.And this aluminium hydroxide is also white in colour.

That's why the colour change in this reaction is almost negligible.

The chemical equation of this reaction is:

Al2(SO4)3 + 6H2O ---> 2Al(OH)3 + 3H2SO4.

[Sufuric acid is colourless that's why it is omitted in this process]
