Question

Given below are certain cations. Using inorganic qualitative analysis, arrange them in increasing group number from 0 to VI.

A. ${Al}^{3 +}$

B. ${Cu}^{2 +}$

C. ${Ba}^{2 +}$

D. ${Co}^{2 +}$

E. ${Mg}^{2 +}$

Choose the correct answer from the options given below.

Accepted Answer

Sol. [Key Concept: Classical cation analysis groups]In the classical qualitative analysis scheme used here, Cu²⁺ belongs to Group II, Al³⁺ to Group III, Co²⁺ to Group IV, Ba²⁺ to Group V and Mg²⁺ to Group VI. Their increasing order is therefore B, A, D, C, E, option (3). These group numbers refer to analytical separation groups.
