Silver diethyldithiocarbamate

[3] The solid should then be rinsed with hot water in order to remove the residual acid salt that will be present.

Granulated zinc is added to the arsine generator flask, which will result in the production of hydrogen because of the presence of acid.

The arsine reacts with the silver diethyldithiocarbamate solution and forms red-colored products (535 nm).

Ultraviolet-visible spectroscopy can be used to determine the concentration of arsenic can be calculated based on Beer's Law.

[11][12] This method of determining arsenic levels in water is compared to the Gutzeit procedure and has the advantages of faster hydrogen gas absorption and more objective color interpretation.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 1: Must be pre-heated before ignition can occur. Flash point over 93 °C (200 °F). E.g. canola oil Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
