Answer

Oxidation occurs when a molecule loses electrons or there is an 'increase' in its oxidation state while gaining of electron or decrease in oxidation state or losing of electrons is termed as reduction. Here in the above equation, the oxidation state of \mathrm {PbO}_ {2} reduces from +4 to +2 while the oxidation state of HCl increases from -1 to 0.

How many half reactions are there in the ion-electron method?

In the ion-electron method (also called the half-reaction method), the redox equation is separated into two half-equations - one for oxidation and one for reduction. Each of these half-reactions is balanced separately and then combined to give the balanced redox equation.

How to make electron gain equal to electron lost?

To make the two equal, multiply the coefficients of all species by integers producing the lowest common multiple between the half-reactions. O:

What is a redox reaction?

A redox reaction is nothing but both oxidation and reduction reactions taking place simultaneously. a) Assign oxidation numbers for each atom in the equation. Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers ).
