Select the correct statement(s).

  1. AGallium has a very low melting point (about ).
  2. BThallium(III) is a strong oxidising agent.
  3. CFor germanium, the +2 state is more stable than the +4 state.
  4. DAqueous acts as a reducing agent.

Answer: A, B, D

Gallium melts just above room temperature, so A is true. Because of the inert pair effect, Tl(III) readily goes to Tl(I), so B is true. Sn(II) is easily oxidised to Sn(IV), so C is true. For Ge the +4 state is more stable (Pb is the first member with a more stable +2), so D is false.
