: The substance that gives away electrons (it gets oxidized). Step-by-Step Algorithm for Balancing ORR
: Note all reactants and products.
: Place these numbers back into the main equation. : The substance that gives away electrons (it gets oxidized)
Determine the stoichiometric coefficients for the oxidizer and reducer. : The substance that gives away electrons (it gets oxidized)
: Highlight elements that have different oxidation states in the reactants vs. the products. Create electronic balance : Write the half-reactions for oxidation and reduction. : The substance that gives away electrons (it gets oxidized)
: The process of gaining electrons, which leads to a decrease in oxidation state.
Find the for the number of electrons transferred.
