Sodium tellurite

Description:
Sodium tellurite, with the chemical formula Na2TeO3 and CAS number 10102-20-2, is an inorganic compound that appears as a white or colorless crystalline solid. It is the sodium salt of tellurite, which is derived from tellurium, a metalloid. Sodium tellurite is soluble in water, and its solutions can exhibit a slight alkaline pH. The compound is known for its use in various applications, including as a reagent in analytical chemistry and as a source of tellurite ions in biological studies. In biological contexts, sodium tellurite has been studied for its antimicrobial properties, particularly against certain bacteria and fungi. However, it is important to handle this compound with care, as tellurium and its compounds can be toxic in certain concentrations. Sodium tellurite can also participate in redox reactions, making it useful in various chemical syntheses. Overall, sodium tellurite is a versatile compound with significant relevance in both industrial and research settings.
