This in all probability boils right down to a similar component because of fact the oxidation selection technique. redox reactions; class-11; Share It On Facebook Twitter Email. Scientists J a tle and Lamer introduced the ion-electron method for balancing equations. This is necessary, because of law of mass action says that the total mass of reactants before is equal to the total mass of products after reaction. Underline The Reducing Agent And Encircle The Oxidizing Agent. This probable boils all the way down to the comparable ingredient because of the fact the oxidation type technique. Balancing equations in chemistry by ion electron method for class 11. In general, the half-reactions are first ...
