Lead (II ) nitrate, a white crystalline solid, the lead (II ) salt of nitric acid. Lead (II ) nitrate is a strong oxidant. It is in contrast to other lead salts readily soluble in water. For this reason, it is toxic.

Representation

Lead (II ) nitrate is produced by the reaction of hot, dilute nitric acid (1) Lead, or (2 ), lead (II ) oxide:

From the solutions it crystallizes in large, water-clear crystals.

The reaction of lead (II ) carbonate with nitric acid, also provides lead (II ) nitrate with the formation of carbon dioxide:

Properties

In contrast to many other lead (II ) salts such as lead (II ) chloride and lead ( II) sulfate is free of lead (II) nitrate, readily soluble in water.

When heated lead (II ) nitrate up to its decomposition temperature of 470 ° C, so it converts to form nitrogen and oxygen in lead (II ) oxide to:

Therefore, this chemical reaction is suitable in the laboratory for the formation of small amounts of the gas nitrogen dioxide. Because of the release of oxygen is lead (II ) nitrate used in the synthesis of dyes as the oxidant.

Toxicity

Lead nitrate is toxic, teratogenic and may impair fertility. It can, even if only in a negligible amount will be absorbed through the skin. Moreover, it is by him a danger to the environment because it is toxic to aquatic organisms.

Use

Use will lead (II ) nitrate continue in the production of textile mordant, matches, special explosives, etching solutions and pearl coloring.
