(a)
Interpretation:
The oxidation numbers to the elements in carbonate ion is to be assigned.
Concept introduction:
Oxidation number is the number given to each element in a molecule or a compound that gives an idea about the number of electrons.
The oxidation number is assigned to each element by following a set of rules shown below.
• In an elemental substance, the oxidation number for every atom is zero.
• For a monoatomic ion, the oxidation number is same as the charge on the ion.
• For a combined oxygen, the oxidation number is
• For a combined hydrogen, the oxidation number is
• In a molecule, the sum of the oxidation numbers of all atoms is equal to the charge on the species.
(b)
Interpretation:
The oxidation numbers to the elements in sulfite ion is to be assigned.

- The iron content of hemoglobin is determined by destroying the hemoglobin molecule and producing small water-soluble ions and molecules. The iron in the aqueous solution is reduced to iron(II) ion and then titrated against potassium permanganate. In the titration, iron(ll) is oxidized to iron(III) and permanganate is reduced to manganese(II) ion. A 5.00-g sample of hemoglobin requires 32.3 mL of a 0.002100 M solution of potassium permanganate. The reaction with permanganate ion is MnO4(aq)+8H+(aq)+5Fe2+(aq)Mn2+(aq)+5Fe3+(aq)+4H2O What is the mass percent of iron in hemoglobin?arrow_forwardWrite the balanced formula and net ionic equation for the reaction that occurs when the contents of the two beakers are added together.
