Approved Tutor Answer11 Months agoThe oxidation state of lead (Pb) in lead dioxide (PbO₂) can be determined by analyzing the compound's composition.
Analyzing the Compound
In PbO₂, there are two oxygen atoms. Oxygen typically has an oxidation state of -2.
Calculating the Total Charge
- For two oxygen atoms: 2 × (-2) = -4
Finding the Oxidation State of Lead
Let the oxidation state of lead be represented as x. The overall charge of the compound is neutral (0), so we can set up the equation:
x + (-4) = 0
Solving for x
By rearranging the equation, we find:
x = +4
Final Result
Thus, the oxidation state of lead in PbO₂ is +4.
