1 mol of CoCl₃·6NH₃ (yellow) gives how many moles of AgCl on adding excess AgNO₃?
A0 mol
B2 mol
C1 mol
D3 mol
Answer & Solution
Correct answer: D. 3 mol
CoCl₃·6NH₃ = **[Co(NH₃)₆]Cl₃**, a 1:3 electrolyte. All 3 Cl⁻ are ionisable (outside coord sphere) → 3 mol AgCl precipitates. The 6 NH₃ are in the coord sphere (secondary valence = 6).
