Sulphide

Posted on December 19, 2017 at 9:42 am.

Sulphide is an inorganic ion of sulphur; it is the simplest ion and is a very strong base. Aqueous solutions of transition metals cations react with sulphide to make precipitates. These precipitates can act as pigments, solar cells and as catalysts. When some mineral sulphides are exposed to gastric acids hydrogen sulphide is produced. Hydrogen Sulphide, some of its salts and most organic sulphides have a strong putrid stench.

At Envirochem we test for sulphide using colourmetrics.

Bromine

Written by Envirochem

Bromine is a brown/red liquid at room temperature. It is very volatile so it doesn’t occur as a liquid naturally; it is rarely found in a salt form, it is most commonly found as bromide in the ocean because of the high solubility of the bromide anion.

Envirochem offers testing for both Bromine using colourmetrics and bromide using an IC.
