Solution
Solution Steps
Step 1: Identify the Cation and Its Oxidation State
The chemical formula $\mathrm{Pb}\left(\mathrm{ClO}_{3}\right)_{4}$ contains lead (Pb) as the cation. The subscript 4 indicates that there are four chlorate ions ($\mathrm{ClO}_{3}^{-}$) associated with one lead ion. Each chlorate ion has a charge of -1.
Step 2: Determine the Total Charge of the Anions
Since there are four chlorate ions, the total negative charge contributed by the chlorate ions is:
\[
4 \times (-1) = -4
\]
Step 3: Determine the Oxidation State of Lead
To balance the -4 charge from the chlorate ions, the lead ion must have a +4 charge. Therefore, the oxidation state of lead in this compound is +4.
Step 4: Name the Compound
The name of the compound is derived from the cation (lead) and the anion (chlorate). Since the lead ion has an oxidation state of +4, it is specified as lead(IV). The anion is chlorate.
