why does dry hcl dos not change its color
Dear student!The dry HCl is a gas which could not produce H+ ion as HCl acid solution in water, and so it does not show acidic behavior and does not changes color of the indicators like litmus paper etc.
Why does not dry HCl gas change the colour of the dry litmus paper?
Why does dry HCl gas does not produce any change in dry litmus paper?
