1.	Statement-1:Sulphur dioxide is a more powerful reducing agent in alkaline medium than in acidic medium. Statement-2:Sulphur dioxides reacts with hydrogen sulphide in presence of moisture and sulphur is precipitated.
Answer» Statement-1 and statement-2 are correct andstatement-2 is the correct explanation for Statement-1 Statement-1 is True, Statement-2 are correct but statement-2 is NOT a correct explanation for Statement-1 Statement-1 is correct, but statement-2 is False. Statement-1 is False, but Statement-2 is correct. Solution :`S_1:2H_2O+SO_2 hArr SO_4^(2-)+4H^(+)+2E^(-)`(increase in `[H^+]` will shift the equilibrium in BACKWARD direction ) `SO_2 +4OH^(-)hArr SO_4^(2-)+2H_2O+2e^(-)`(increase in `[OH^-]` will shift the equilibrium in forward direction ) `S_2:2H_2S+SO_2 overset("moisture")to2H_2O +3S darr`
