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

A. Al3+\mathrm{Al^{3+}} · B. Cu2+\mathrm{Cu^{2+}} · C. Ba2+\mathrm{Ba^{2+}} · D. Co2+\mathrm{Co^{2+}} · E. Mg2+\mathrm{Mg^{2+}}

Choose the correct answer from the options given below:

  1. A.B, C, A, D, E
  2. B.E, C, D, B, A
  3. C.E, A, B, C, D
  4. D.B, A, D, C, E✓

Solution

Qualitative-analysis groups: Cu2+\mathrm{Cu^{2+}} Group II, Al3+\mathrm{Al^{3+}} Group III, Co2+\mathrm{Co^{2+}} Group IV, Ba2+\mathrm{Ba^{2+}} Group V, Mg2+\mathrm{Mg^{2+}} Group VI. Increasing group order: B, A, D, C, E.
