| | POTASSIUM TELLURITE Usage And Synthesis |
| Chemical Properties | Granular, white powder. Hygroscopic;
decomposes at 460–470C. Soluble in water. | | Uses | In 1:50,000 solution for detecting presence of living pathogenic bacteria in sera and vaccines, such organisms forming characteristic black reduction Compounds. | | 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
