The volume (in mL) of 0.1 M

\mathrm{AgN}{\mathrm{O}_3}

required for complete precipitation of chloride ions present in 30 mL of 0.01 M solution of

\left[ {\mathrm{Cr}{{\left( {{\mathrm{H}_2}\mathrm{O}} \right)}_5}\mathrm{Cl}} \right]\mathrm{C}{\mathrm{l}_2}

, as silver chloride is close to

View answer and explanation

Correct option: D

Option D (6) is correct because two chloride ions are outside the coordination sphere, and they will precipitate with silver nitrate, requiring 6 mL of 0.1 M AgNO3.
