When aqueous solutions of potassium iodide and lead nitrate

Acids, Bases and Salts (10)

When aqueous solutions of potassium iodide and lead nitrate are mixed, an insoluble substance separates out. The chemical equation for the reaction involved is:

  1. KI + PbNO3 → PbI + KNO3
  2. 2KI + Pb(NO3)2 → PbI2 + 2KNO3
  3. KI + Pb(NO3)2 → PbI + KNO3
  4. KI + PbNO3  →  PbI2 + KNO3

Answer

(B) 2KI + Pb(NO3)2 → PbI2 + 2KNO3
