If a hydrate of the formula decomposes when heated to produce HCl, what change would you expect to occur when a piece of blue litmus paper is held in the path of the vapor released? [Litmus paper is paper impregnated with an acid-base indicator that is blue in the presence of base and red in the presence of acid.]
