there is no ms for this paper so i checked out the examiners report which said Three different observations were required for the reaction between zinc and aqueous copper(II)
sulphate. Possible answers included: zinc dissolves, reacts; a red or copper deposit; solution
warms up, bubbles, effervesces or a gas is evolved.
