Tellurium forms oxides of the formula `TeO, TeO_(2) and TeO_(3)`. What is the nature of these tellurium oxides ?

Text Solution

Verified by Experts

TeO (oxidation number of Te is +2) is basic.
`TeO_2` (oxidation number of Te is +4) is amphoteric.
`TeO_3` (oxidation number of Te is +6) is acidic.
As the oxidation number of the element forming oxide increases, the acidic nature also increases.
