1.	State and explain the reactions, if any, of the following metals with a solution of copper sulphate :(a) Gold (b) Copper (c) Zinc (d) Mercury
Answer» (a) No displacement reaction will take place because go ld is less reactive than copper. (b) No reaction will take place between copper and copper sulphate solution ; there is no reaction possible. (c) Zinc displaces copper from copper sulphate solution to form zinc sulphate solution and copper metal because zinc is m ore reactive than copper . (d) No displacement reaction will take place because mercury is less reactive than copper
