Ans: – The dry cheap or blue litmus papers when will cake in contact with the hydrochloride acid then we will see its colour become red as the H(+) present in HCl turns to this change.

If this makes moisture then we will see if will act as a base so in that case the colour of this in contact with the hydrogen chloride make this yellow in colour.
