lead ii nitrate solution is an inorganic compound of the formula Pb(NO3)2. It is used as a source of lead (II) oxide in the production of other lead compounds. It was first commercially produced in the nineteenth century.
It occurs as a white or colourless crystal, with an average relative density of 4.53. It is soluble in water, liquid ammonia, and ethanol but slightly insoluble in concentrated nitric acid. It can react with concentrated hydrochloric acid to form complex chlorinated lead acid, or with concentrated alkali chloride solution to produce complex chlorinated lead nitrate salt; it has a strong oxidizing activity and may incite combustion and explosion when mixed with organic matter, reducing agent, or combustible substance such as sulfur and phosphorus.
The solution is a moderately toxic substance. It is an irritant to eye and skin and may be hazardous to the respiratory tract in large doses. It may cause respiratory failure, asphyxia, and pulmonary edema.
To prepare a solution of this compound, dissolve 0.16 g of lead nitrate in 200 mL water. Add 10 mL of conc. HNO3 and dilute to 1000 mL with water.
Titrate the solution with EDTA until it changes color to a bright yellow. This is the end of the titration process.
Potassium iodide can be mixed with lead nitrate in a solution to introduce students to the double replacement reaction. A precipitate of lead iodide appears when the iodide reacts with the nitrate.
