Question

If the excess of $AgN{O}_3$ solution is added to $100mL$ of a $0.024M$ solution of dichloro bis (ethylenediamine) cobalt (III) chloride, how many molecules of $AgCl$ would be precipitated?

• A. $0.0012$
• B. $0.0016$
• C. $0.0024$
• D. $0.0048$

Answer 1

The correct option is C $0.0024$

Here answer is option C
Dichlorobis(ethylenediamine)cobalt(III)chloride has
1) two chloro ligands$\left(C{l}^{-}\right)$ in the inner coordination sphere.
2)two ethylenenediamine ligands $(N{H}_2-C{H}_2-C{H}_2-N{H}_2)$ in the inner coordination sphere.
3)a chloride $\left(C{l}^{-}\right)$ligand coordinated on the outer coordination sphere.
4)cobalt(III), which has an oxidation state of (+3)
