TA Laboratory Date - Section Name Experiment 12-Post-lab Questions 1. Consider the balanced redox reaction taking place in an acidic aqueous solution vo," (aq) +SO,'(aq) Vo(aq) +0,- (aq) The unbalanced oxidative half-reaction for this redox reaction is: VO, (aq) → VO" (ag) Because the reaction takes place in aqueous solution, the reaction can be balanced by adding water. 2. Add water to reaction (la) to balance the oxygen. This will give reaction (1b). (1b) Because the reaction takes place in an acidic solution, the reaction can be balanced by adding H'(aq). b. Add Hap) to reaction (1b) to balance the hydrogen. This will give reaction (le). Because this is a half-reaction, the reaction can be balanced by adding electrons. c. Adde to reaction (le) to balance the charge. This will give reaction (1d). The unbalanced reductive half-reaction for the redox reaction is: SO, (aq) → SO, (ag) a. Add water to reaction (2a) to balance the oxygen. This will give reaction (2b). b. Add Haq) to reaction (2b) to balance the hydrogen. This will give reaction (2e). e. Add to reaction (2c) to balance the charge. This will give reaction (2d). d. Combine reactions (Id) and (20) to produce a "whole" reaction that is balanced and does not show electrons as a reactant or a product.
