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.

Final Answer

\(\boxed{\text{lead(IV) sulfite}}\)
