Oxidation states method

Balancing Redox Reactions by the Change in Oxidation State Method... 

Use the change in oxidation state method to balance the above equation in an acidic medium. 

When this occurs, the electron contribution of the ligand is increased by two. In die neutral atom scheme, it is now a three-electron donor and by the oxidation state method, a four-electron donor. The complex Rh CO C has two bridging chloro ligands ... 

In the oxidation state method, the ligand is viewed as a coordinated nitrosyl ion. NO+, when linear and a coordinated NO" when bent it is a two-electron donor in both forms. 

Oxidation-reduction reactions are often complicated, which means that it can be difficult to balance their equations by simple inspection. Two methods for balancing redox reactions will be considered here (1) the oxidation states method and (2) the half-reaction method. 

In using the oxidation states method to balance an oxidation-reduction equation, we find the coefficients for the reactants that will make the total increase in oxidation state balance the total decrease. The remainder of the equation is then balanced by inspection. 

The procedures for balancing an oxidation-reduction equation by the oxidation states method are summarized below. 

Balancing an Oxidation-Reduction Equation by the Oxidation States Method... 

Balance each of the following oxidation-reduction reactions by using the oxidation states method. 

The principles of oxidation-reduction provide the basis of two simple systematic methods for balancing these equations. If all the products of reaction are known, the balancing may be done either by the ion-electron method or by the oxidation-state method. (The two methods are compared following Problem 11.8.) After students have acquired more experience, they will be able to predict some or all of the principal products if they keep in mind such facts as the following ... 

The first partly filled skeleton equation could have been written in terms of NOJ rather than H NO). For variety in the subsequent solved problems, the neutral-compound notation will be used in the oxidation-state method, and the ionic notation in the ion-electron method. 

Some chemists prefer to use the ion-electron method for oxidation-reduction reactions carried out in dilute aqueous solutions, where free ions have a more or less independent existence, and to use the oxidation-state method for oxidation-reduction reactions in other liquid media, in solids, or in gases. 

Balancing Oxidation-Reduction Equations Oxidation States Method of Balancing Oxidation-Reduction Reactions... 

Equations for oxidation-reduction reactions can be balanced by the oxidation states method... 

Consider the steps involved in balancing oxidation-reduction reactions by using oxidation states. The key to the oxidation states method is to equalize the electrons lost by the species oxidized with the electrons gained by the species reduced. First of all, how do you recognize what is oxidized and what is reduced Second, how do you balance the electrons lost with the electrons gained Once the electrons are balanced, what else is needed to balance the oxidation-reduction reaction ...
