2.6 mL of [AgI] Ag+ sol is coagulated by 13 mL of 0.001 M KI. What is flocculation value of KI?

[AgI]Ag++I−⟶AgI↓+AgI↓13mL of 0.001 M KI 13 × 0.001 millimoles                                       13mL of 0.001MKI13×0.001 millimoles ∴1000mL of [AgI]Ag+require =13×0.0012.6×1000 millimoles of KI = 5 millimoles per litreThus, flocculation value of KI = 5
