Analysis:  Redox Half reaction of titration #1. Fe2+, SO42-, NH4+, H2O, K+, MnO4-, H+

Finding concentration of KMnO4:

SOA:​MnO4- + 8H+ + 5e- → Mn2+ + 4H2O 

SRA:​(Fe2+ → Fe3+ + e-) x 5


Predicted Redox Reaction: MnO4- + 8 H+ + 5 Fe2+ → Mn2+ + 4 H2O + 5 Fe3+



​Therefore, the concentration of KMnO4(aq) is 0.00728 mol/L.



Finding concentration of H2O2:


Redox half reaction of titration #2







Predicted Redox Reaction: 


Using Stoichiometry to find Concentration of H2O2.



Since is diluted by a factor of 40, the concentration is multiplied by 40.




Percent concentration of H2O2(aq) is 2.80% according to the table in the textbook.​
