EXPERIMENT \#11 PRELAB EXERCISE Redox Titration (Molarity Version) DATE OF EXPERIMENT: LAB DAY \& TIME: NAME ID. No. 1. Balance the following redox reaction under acidic conditions. (3 marks) C2O42(aq)+MnO4(aq)CO2(g)+Mn2+(aq) Given: MnO4(aq)+5e+8H(aq)Mn2+(aq)+4H2O(l)2 And C2O42(aq)2CO2(g)+2e5 2. A 5.00 gram sample of impure sodium oxalate required 36.91mL of 0.100MKMnO4 to reach the endpoint. What was the percent purity of the sample? You will need the balanced equation from question \#1.
