Redox balancing strategy

Strategy Follow the general procedure for writing and balancing redox equations in Chapter 4 and reviewed in Chapter 18. Note that because nitric acid is strong, it should be represented as H+ and N03 ions. 

The strategy used for this and other redox titrations is outlined in Figure 4.5. As with acid-base titrations, the general idea is to measure a known amount of one substance—in this case, H2C204—and use mole ratios from the balanced equation to find the number of moles of the second substance—in this case, KMn04—necessary for complete reaction. With the molar amount of KMn04 thus... 

Strategy We follow the procedure for balancing redox reactions presented in Section 19.1 of the text. 

Strategy We foUow the preceding procedure for balancing redox equations. Note that the reaction takes place in a basic medium. 

Strategy Follow the procedure for balancing redox equations by the ion-electron method. The reaction takes place in a basic medium, so any ions that appear in the two half-reactions must be neutralized by adding an equal nttmber of OH ions to both sides of the equation.
