HER'S UR ANSWER

Explanation:

Dry HCl gas does not affect a dry blue litmus paper, whereas it changes a moist blue litmus paper to red because dry HCL does not have water that means it does not produce H3O- IONS (HYDRONIUM IONS) ..

its pH value on pH scale is 0-1

We can know this by observing pH scale. When we put dry hcl on it it turns red (0-1)
