Gas X is also a good (iii)……………(oxidising/reducing) agent, which in excess reacts with a greenish-yellow gas to form dense white fumes of (iv) …………… (hydrogen chloride/ammonium chloride).
Answer
An aqueous solution of gas X turns red litmus blue, so it must contain hydroxyl ions. When this solution is added in excess to copper sulphate solution, it turns to deep blue solution. Gas X is also a good reducing agent, which in excess reacts with a greenish-yellow gas to form dense white fumes of ammonium chloride.
