Question

How would you test for the presence of chloride ions in solution?

Answer 1

Identification,

If you want to test whether there is chloride ions are present or not in the solution, then you can follow the procedure given below.

Now at first you need to have some instruments.They are listed below-

(1) Test tubes
(2) Bunsen burner
(3) Boiling test tube
(4) Pipette
(5) Test tube holder
and (6) Filler

Also you need three chemicals named - manganese dioxide, sulphuric acid and manganous chloride.

Take a test tube and put some chloride salt to it with the help of Pipette.Then add a small amount of MnO2 in it.After that hold it with the test tube holder and heat it with bunsen burner.after sometime move it from the burner and with the help of filler add few drops of H2SO4.If you observe carefully you will find greenish fumes evolving from the test tube and oily coating on the surfaces of the test tube.

This indicates that the salt contains chloride ions.

If any solute is processed in the same manner and oily coating appears in the tubes body, then the solute will have chloride ions.

That's it
