Tellurite is a oxyanion of tellurium with the formula TeO²⁻
₃. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO
₂), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite.
