Splet28. mar. 2024 · Explanation: Lead (Pb) has 2 positive oxidation states, +4 and +2. Sulfur (S) has 3 oxidation states: +6, +4, and -2. Since lead creates a positive ion, sulfur must be a negative ion to balance the charges. There are 2 atoms of sulfur, each with a charge of -2. Therefore, their overall charge is -4, because 2* -2= -4.
