Here are a few questions and answers which the students can use as they prepare for their exams:

Question: Identify the substance oxidised, reduced, oxidising agent and reducing agent of the following reaction:
2AgBrs+C6H6O2aq→2Ags+2HBraq+C6H4O2aq

Answer: 2AgBrs+C6H6O2aq→2Ags+2HBraq+C6H4O2aq
The gain of electrons leads to reduction:
Ag++e-→Ags
The oxidation number of Ag changes from +1 to 0.
The loss of electrons leads to oxidation: C6H6O2aq→C6H4O2aq+2H++2eHere, the oxidation number of C changes from -13 to 0.
Hence, the substance oxidised→C6H6O2
And, the substance reduced→AgBr
Therefore, the oxidising agent →AgBr
And, the reducing agent →C6H6O2

Question: Identify the substance oxidized, reduced, oxidising agent, and reducing agent for the following reaction:HCHOl + 2Ag(NH3)2 +(aq) + 3OH-(aq) → 2Ag(s) + HCOO-(aq) + 4NH3(aq) +2H2O(l)
Answer: HCHO(l) + 2Ag(NH3)2+(aq) +3OH-(aq) → 2Ag(s) + HCOO-(aq) + 4NH3(aq) + 2H2O(l)
The loss of electron(s) leads to oxidation:
HCHO(l) + H2O(l) →HCOO-(aq) + 3H+ + 2e- The O.N. of C changes from 0 to +2 The gain of electron(s)
leads to reduction: Ag(NH3)2+(aq) + e- → Ag(s) + 2NH3(aq) + 2H2O(l) The O.N. of Ag changes from +1 to 0
Hence, the oxidised substance is HCHO
and, the reduced substance is Ag(NH3)2+
Therefore, the oxidising agent will be Ag(NH3)2+ and, the reducing agent will be HCHO.

Class 11 Chemistry Chapter 8: Chapter Description

Chemistry deals with the change of one kind of matter to another involving some chemical reactions. This change involves various kinds of reactions and Redox Reaction is one of them. Redox reactions are one of the important kinds of reactions involved in various chemical processes. A number of phenomena, both physical and biological, are concerned with redox reactions. The redox reactions find a wide range of applications in pharmaceutical, biological, industrial, metallurgical and agricultural areas.

Redox reactions are the reactions in which oxidation and reduction reactions occur simultaneously. The discussions in this chapter start with a basic understanding of redox reactions and learning the basic definitions and terminologies. Thereafter, the redox mechanisms are studied. Lastly, balancing the chemical equations using redox reactions and reactions at the electrode is discussed.
