हिन्दीGiven below are certain cations. Using inorganic qualitative analysis, arrange them in increasing group number from 0 to VI.\nA. \( \text{Al}^{3+} \)\nB. \( \text{Cu}^{2+} \)\nC. \( \text{Ba}^{2+} \)\nD. \( \text{Co}^{2+} \)\nE. \( \text{Mg}^{2+} \) \nChoose the correct answer from the options given below:
Correct answer · Option 3
B, A, D, C, E
Explanation
In qualitative analysis of cations, the groups are: \( \text{Cu}^{2+} \) (Group II), \( \text{Al}^{3+} \) (Group III), \( \text{Co}^{2+} \) (Group IV), \( \text{Ba}^{2+} \) (Group V), and \( \text{Mg}^{2+} \) (Group VI). Thus, the correct increasing order of group numbers is B, A, D, C, E.
