(iii) Give two uses of tetraoxosulphate (VI) acid.

(b)(i) Describe a suitable laboratory procedure for preparing a sample of zinc tetraoxosulphate (VI) crystals, starting from zinc oxide.

(ii) Write two equations to show why zinc oxide is classified as an amphoteric oxide.

(c) Zinc reacts with copper (II) tetraoxosulphate (VI) according to the following equation: Zn + CuSO\(_4\) -> ZnSO\(_4\) + Cu
