Q. A 1 : 3 electrolyte in an aqueous solution is
A) [Co(NH₃)₃(NO₂)₃]
B) [CoCl₂(NH₃)₄]Cl
C) [CoCl(NH₃)₅]Cl₂
D) [Co(NH₃)₆]Cl₃
Explanation
[Solution from source] [Co(NH₃)₆]Cl₃ gives one complex cation and three Cl⁻ (1 : 3). [CoCl(NH₃)₅]Cl₂ gives 1 : 2, [CoCl₂(NH₃)₄]Cl gives 1 : 1, and [Co(NH₃)₃(NO₂)₃] is a non-electrolyte. Answer (4).
