Question

when a mole of [CoBr(NH3)5]SO4 is dissolved in water the number of ions formed is a) 4 b) 2 c) 6​

Answer 1

Answer:

Answer. But for case of neutral complex we need a certain dianion, as sulphate (SO4)2-, which goes in. When this will be dissolved in H2O i.e aqueous solution, the complex and sulphate ion will be enticed as separate entities. Hence 2 is the answer.
