Question
What is the oxidation number of lead in PbO2Group of answer choices2-1+4+2+
Solution
The oxidation number of lead in PbO2 is +4.
Here's the step-by-step process:
- Oxygen generally has an oxidation state of -2 in compounds.
- Since the compound is neutral overall, the sum of the oxidation states of all atoms must be zero.
- There are two oxygen atoms, so the total oxidation state for the oxygen in the compound is -4 (2 atoms * -2 oxidation state/atom = -4).
- To balance this out and make the total oxidation state of the compound zero, the lead atom must have an oxidation state of +4.
