2 PB(NO3)2 = 2 PBO + 4 NO2 + O2 Copy to clipboard
Reaction type: decomposition
Lead nitrate is a white crystalline solid. The material is soluble in water. It is noncombustible but it will accelerate the burning of combustible materials. If large quantities of the material are involved in the fire an explosion may result. Prolonged exposure of the material to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving this material.
Oxygen
