Question

In which one of the pairs of ion given, there is an ion that forms a coordination compound with both aqueous sodium hydroxide and ammonia and an other ion that forms a coordination compound only with aqueous sodium hydroxide?

Accepted Answer

Correct answer: B. (b) : Zn^2+ ion reacts with aq. NaOH and NH_3 and forms a coordination compound. Zn^2++4 NaOH ( Zn ( OH )_4 )^2-+4 Na^+ Zn^2++4 NH_3 ( Zn ( NH_3 )_4 )^2+ But, Al^3+ ion reacts only with NaOH. Al^3++4 NaOH ( Al ( OH )_4 )^++4 Na^+
