Classical Concept In a redox reaction oxidation and reduction occurs simultaneously. Candidates can click on the subject wise link to get the same. In an ion, the algebraic sum is equal to the charge on the ion. As oxygen is more electronegative than Cl. All these reactions are always accompanied by energy change in the form of heat, light or electricity. Molecules of most electronegative elements such as O2, O3, halogens. When a redox reaction takes place, both oxidation and reduction reactions also occur simultaneously. Oxidation number of an element may be a whole number (positive or negative) or fractional or zero.

A reaction in which oxidation and reduction are carried out separately in two separate half-cells, is known as indirect redox reaction. (i) Intermolecular redox reactions In such reactions, oxidation and reduction take place separately in two compounds. Redox titrations are used to determine the strength of a reductant (or) oxidant by using a redox sensitive indicator.. Redox titrations can be performed using oxidising agents such as potassium permanganate, potassium dichromate and iodine. e.g.. (ii) Intramolecular redox reactions In these reactions, oxidation and reduction take place in a single compound. For p-block elements [Except F and 0], the highest oxidation number is equal to their group number and lowest oxidation number is equal to the group number minus eight. Also, this reaction oxidation and reduction occurs at the same time. To equalize the number of electrons in both reactions, we multiply oxidation half reaction by 6 and write as: 6Fe 2+ --> 6Fe 3+ +6e-Step 5: We add the two half reactions to achieve the overall reaction and cancel the electrons on each side .This give us net ionic equation: 6Fe 2+ + Cr 2 O 7 2- + 14 H +- … Candidates who are studying in Class 11 can also check Class 11 NCERT Solutions from here.
