Question

How many ions will be furnished by $CoCl_{3}\,.\,\,6NH_{3}$ ?

• A. 3
• B. 4
• C. either [a] or [b]
• D. 2

Answer 1

Answer: (C)

either [a] or [b]

Answer 2

$CoCl _{3} \cdot 6 NH _{3}$ form the compounds $\left[ Co \left( NH _{3}\right)_{6} Cl _{3}\right.$ or $\left[ Co \left( NH _{3}\right)_{5} Cl \right] Cl _{2}$
So, the above compound forms $4$ or $3$ ions in the solution.
