Question

What is observed when the sodium sulphite is added to the copper chloride solution

Answer 1

Answer:

Aqueous sodium chloride, NaCl, will not react with aqueous copper(II) sulfate, CuSO

4

, because the two potential products are soluble in an aqueous solution.

The chemical equation given is actually incorrect because copper (ll) chloride, CuCl

2

, is not insoluble in aqueous solution. In fact, it is quite soluble.

This means that the reaction does not produce an insoluble solid that precipitates out of solution.

Sodium chloride and copper(II) sulfate are both soluble ionic compounds that dissociate completely in an aqueous solution and exist as ions in the solution.
