Question

Sr.No. Experiment procedure
1 The colour and the nature of the sodium sulphate solution before the experiment. 2. The colour and the nature of the barium chloride solution before the experiment.
3 The colour and the nature of the mixture resulting on mixing the two solution into each other.​

Answer 1

Answer:

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

Answer 2

Answer:

When two solutions are mixed and the mixture becomes cloudy, it suggests the formation of an insoluble substance. The chemical reaction that occurs here is a precipitation reaction and the insoluble substance formed is called precipitate. This is an example of a double displacement reaction.

For example:
