Question

1 g of solid sodium chloride is taken in a clean and dry test tube and 2 mL of conc. sulphuric acid is added to it. If the gas evolved is tested first with dry and then with wet blue litmus paper, in which case will the litmus paper change colour ? Give reason for your answer. What inference can be drawn about the nature of the evolved gas ? Support your answer with chemical equation for the reaction

Answer 1

When it is concentrated with Sulphuric acid, it is added to NaCl, Sodium bisulphate and HCL gas.

This is determined with reactions which takes place at the same time.

It is taking between NaCl and H2SO4 and HCL.

So gas is released on reactions takes place in nature acid turns to blue litmus.

This is because it has been changing with the hydrogen ions.

Answer 2

Answer:

Explanation:

The wet blue litmus paper change

Reason=hydrogen ions are produced by HCL in the presence of water

It is acidic in nature

Chemical=HCL + H2O -> H3oplus ions +cl minus ions
