Question

In a series of compounds formed on reactions of cobalt (III) chloride with ammonia, it was found that some of the chloride ions could be precipitated as AgCl on adding excess silver nitrate solution in cold but some remained in solution. Considering that separate aqueous solution of each compound show electrical conductance , then select CORRECT statement(s) about compound(s).

Options:(select one or more)

Answer:

C, D

Solution:

$[Co (NH_{3})_{6}] Cl_{3} \to$ Yellow

$[Co (NH_{3})_{5} Cl] Cl_{2} \to$ Purple

$[Co (NH_{3})_{4} Cl_{2}] Cl \to$ Green

$[Co (NH_{3})_{4} Cl_{2}] Cl \to$ Violet
