Question

How many ions will be furnished by $CoC{l}_3.6N{H}_3$ ?

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

Answer 1

Answer: (C)

$CoC{l}_3\cdot 6N{H}_3$ form the compounds $[Co{\left(N{H}_3\right)}_{6}C{l}_3$ or $\left[Co{\left(N{H}_3\right)}_{5}Cl\right]C{l}_2$
So, the above compound forms $4$ or $3$ ions in the solution.
