SILVER NITRITE Chemical Properties,Usage,Production

Chemical Properties

powder

Uses

Silver nitrite is used in the silver plating process, hair dye, inks, permanent marker pens and determination of chloride ions in water and drilling fluids. It is used as Tollen?s reagent and used in the formation of aniline and nitro compounds in victor mayer reactions.

Uses

For preparation of standard NaNO2 solution for water analysis; preparation of aliphatic nitro-compounds; as reagent for primary, secondary, and tertiary alcohols.

Hazard

Highly toxic.

Purification Methods

Crystallise the salt from hot conductivity water (70mL/g) in the dark. Dry it in the dark under vacuum. [Glemser & Sauer in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 1048 1963.]
