NESSLER'S REAGENT Chemical Properties,Uses,Production

Chemical Properties

light yellow liquid

Uses

Detecting the presence of ammonia, particularly in very small amounts.

Definition

Solution of mercuric iodide in potassium iodide.

General Description

Odorless yellow crystals. Crystallizes with either one, two or three molecules of water. Soluble in water and denser than water. Commercially available in the anhydrous form. Highly toxic by ingestion, inhalation, and skin absorption.

Air & Water Reactions

Deliquescent. Very water soluble.

Reactivity Profile

MERCURIC POTASSIUM IODIDE is incompatible with acetylene, ammonia, chlorine dioxide, azides, calcium (amalgam formation), sodium carbide, lithium, rubidium, copper . NESSLER'S REAGENT behave in aqueous solution as a weak acid.

Hazard

Highly toxic by ingestion, inhalation, and skin absorption.

Health Hazard

Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.

Safety Profile

A poison. Moderately toxic by skin contact and intraperitoneal routes. When heated to decomposition it emits very toxic fumes of Hg, K2O, and I-. See also MERCURY.
