Question

balancing of redox reaction​

Answer 1

SOLUTION :-

Simple Redox Reactions :-

• Write the oxidation and reduction half-reactions for the species that is reduced or oxidized.
• Multiply the half-reactions by the appropriate number so that they have equal numbers of electrons.
• Add the two equations to cancel out the electrons. The equation should be balanced.

Balancing Redox Reactions: Oxidation-Number-Change Method

One way to balance redox reactions is by keeping track of the electron transfer using the oxidation numbers of each of the atoms. For the oxidation-number-change method, start with the unbalanced skeleton equation. The example below is for the reaction of iron(III) oxide with carbon monoxide. This reaction is one that takes place in a blast furnace during the processing of iron ore into metallic iron

Answer 2

Guidelines for Balancing Redox Equations:

• Determine the oxidation states of each species.
• Write each half reaction and for each: ...
• Balance the number of electrons transferred for each half reaction using the appropriate factor so that the electrons cancel.
• Add the two half-reactions together and simplify if necessary.

We can identify redox reactions by checking for changes in oxidation number. Redox reactions can be split into oxidation and reduction half-reactions. We can use the half-reaction method to balance redox reactions, which requires that both mass and charge are balanced.
