WebRedox (reduction–oxidation, / ˈ r ɛ d ɒ k s / RED-oks, / ˈ r iː d ɒ k s / REE-doks) is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation … WebCr+3 + Cl-1 = Cr+3 + Cl-12. To balance the unbalanced chloride molecule charges, we add 2 in front of the chloride on L.H.S. We get, Cr+3 + (2)Cl-1 = Cr+3 + Cl-12. Now, the equation is balanced with 2 Chloride’s (Cl) with total charge -2 and 3 Chromium’s with total charge +3 on both sides. This is how the redox equations are balanced.
