Question

Assign reasons for the following :
(i) Copper (I) ion is not known in aqueous solution.
(ii) Actinoids exhibit greater range of oxidation states than lanthanoids..​

Answer 1

(ii) Actinoids exhibit greater range of oxidation states than Lanthanoids. in aqueous to give Cu and Cu2+ ion. Due to more reduction electrode potential value of Cu+, it undergoes oxidation reaction quite feasible. Hence, the copper (I) ion is not known in aqueous solution.
