What are the oxidizing agents and reducing agents in:

a) ClO3- (aq) + 5Cl-(aq)+6H3O+(aq) -> 3Cl2(aq)+9H2O(l)

b) CaCO3(s) + SO3(aq) -> CaSO4(s) + CO2(g)

Answer #1

a)
oxidation of Cl in ClO3- is +5
oxidation of Cl in Cl- is -1
oxidation state of Cl in Cl2 is 0
So,
Cl in ClO3- is reduced
This makes ClO3- as oxidisng agent
Cl in Cl- is oxidised
This makes Cl- as reducing agent

b)
oxidation state of C is +4 on both sides
oxidation state of Ca is +2 on both sides
oxidation state of O is -2 on both sides
oxidation state of S is +6 on both sides

So, nothing is oxidised or reduced
Hence there is no oxidising or reducing agent

Redox titrations are used to determine the amounts of oxidizing and reducing agents in solution. For example, a solution of hydrogen peroxide, H2O2, can be titrated against a solution of potassium permanganate, KMnO4. The following equation represents the reaction: 2KMnO4(aq)+H2O2(aq)+3H2SO4(aq)→3O2(g)+2MnSO4(aq)+K2SO4(aq)+4H2O(l) A certain amount of hydrogen peroxide was dissolved in 100. mL of water and then titrated with 1.68 M KMnO4. What mass of H2O2 was dissolved if the titration required 21.8 mL of the KMnO4 solution?
