Identify the substance oxidized reduced, oxidizing agent and a reducing agent for each of the following reactions:
2AgBr (s) + C6H6O2 (aq) → 2Ag(s) + 2HBr (aq) + C6H4O2(aq)
Oxidised substance:- C6H6O2
Reducing agent:- C6H6O2
Explanation:- Oxidising agent is a reagent which can increase the O.N. of an element in a given substance.
Here, AgBr helps carbon in C6H6O2 to increase its oxidation number.
The reduced substance is a reagent whose oxidation state has been decreased.
Here, in this case, Ag in AgBr has + 1 oxidation state and the O.N. is reduced to zero as Ag in the product side is present in zero O.N. (its elemental form)
The oxidised substance is a reagent whose oxidation state has been decreased.
C in C6H6O2 has O.N. of -0.33 which is being increased to zero in C6H4O2
Reducing Agent is a reagent which lowers the oxidation number of an element in a given substance.
C6H6O2 helps Ag of AgBr to decrease its oxidation state.
