Question

Chemical test to distinguish between sodium sulphate and ammonium sulphate

Answer 1

Hi,

The answer to your question is as follows,

Distinguishing Chemical test between sodium sulphate and ammonium sulphate:

Add ammonium sulphate in sodium sulphate and heat. In no time, fumes of ammonia will start to emerge in the air and a distinguish smell is detected.

Ammonia has a very distinct smell hence it is easily recognized.

The chemical equation of such a solution is as follows;

NH42SO4 + 2NaOH → 2NH3 + Na2SO4+2H2O

Hope this answer helped.

Thanks for asking

Answer 2

Hola mate

Here is your answer -

Distinguishing test between ammonium sulphate and sodium sulphate :

If you heat ammonium sulphate with calcium oxide, smell of ammonia will come out.

(NH4)2SO4 + CaO → CaSO4 + 2NH3 +H2O

 If  a wet glass road by HCl is hold on the evolved gas, white fumes of NH4Cl will form.

NH3 + HCl → NH4Cl

 But sodium sulphate (Na2SO4) does not respond to above mentioned tests.

If flame test is performed with Na2SO4, a golden yellow flame will be observed.
