Q21.5P - Chemistry: Molecular Nature Of Matter And Change

Question

During the redox balancing process, what step is taken to ensure that loss equals gain?

Step-by-Step Solution

Answer

To make the gain and loss of electrons equal, half-reactions are multiplied by appropriate integers.

Step 1: Redox balancing process means,

Redox responses must be balanced. The component half-reactions for oxidation and reduction must be balanced in order to describe the total electrochemical reaction for a redox process. In general, this entails supplying H+, OH, ${\text{H}}_2\text{O}$, and electrons to compensate for oxidation changes in aqueous solutions.

Step 2: Determining the steps taken during the redox balancing process

We verify that gained equals ${\mathrm{e}}^{-}$ lost throughout the redox balancing procedure by multiplying both half-reactions by appropriate integers (the lowest common multiple).
