Provide the correct IUPAC name for $\mathrm{Pb}\left(\mathrm{SO}_{3}\right)_{2}$.
Solution
Solution Steps
Step 1: Identify the Cation and Anion
The compound \(\mathrm{Pb}\left(\mathrm{SO}_{3}\right)_{2}\) consists of a lead cation (\(\mathrm{Pb}\)) and a sulfite anion (\(\mathrm{SO}_{3}^{2-}\)).
Step 2: Determine the Oxidation State of the Cation
The sulfite anion \(\mathrm{SO}_{3}^{2-}\) has a charge of \(-2\).
Since there are two sulfite ions, the total negative charge is \(-4\).
To balance this, the lead cation must have a charge of \(+4\).
Therefore, the oxidation state of lead in this compound is \(+4\).
Step 3: Write the IUPAC Name
The IUPAC name for a compound with lead in the \(+4\) oxidation state is "lead(IV)".
The anion is sulfite.
Combine the names to get the IUPAC name: lead(IV) sulfite.
