Answer:
Because in dry state HCl dosent release h+ ions so it's acidic property are not shown. Whereas in water it dissociates into H+ and cl- so the presence of h+ shows it acidic property .
Explanation:
Acids shows acid property only when H+ ion is released and then only then they change the colour of litmus paper.
Answer:we know that the colour of litmus is changed by H+ ions of an acid
Dry hcl does dissociate to give H+ ions.
Acids dissociate to give ions only in aqueous medium.
Since in this case neither hcl is aqueous form nor is the litmus wet so the colour of litmus paper does not change
