Question

Why dry HCL doesn't change color of litmus paper​

Answer 1

Explanation:

In case of dry HCl gas, there is no presence of water and so, the dye on litmus paper cannot react with the gas. So, any dry gas will not give any change in the colour of litmus paper

Answer 2

Answer:

Colour of the litmus paper is changed by the hydrogen ions. Dry HCl gas does not contain

h+ ions. It is only in the aqueous solution that an acid dissociates to give ions. Since in this case, neither HCl is in the aqueous form nor the litmus paper is wet, therefore, the colour of the litmus paper does not change
