Uses
Potassium tellurite along with agar may be used as a component of a selective medium for growth of bacteria.
Definition
ChEBI: A potassium salt consisting of potassium and tellurite ions in a 2:1 ratio.
General Description
Potassium tellurite is a hygroscopic granular white powder. It decomposes at 460-470oC.
Safety Profile
A poison by an unspecified route. Human systemic effects by ingestion: sleep dsturbance, anorexia, nausea. When heated to decomposition it emits toxic fumes of K2O and Te. See also TELLURIUM compounds.
