hydrogen peroxide titration, concentration of KMnO4 is 0.025 and
the concentration of H2O2 from the mol ratio is 0.882 M
o Estimated Concentration of Diluted Peroxide: . Remember when we had a 1:1 ratio we wanted the concentrations of NaOH and HCl to be similar. So if NaOH was 0.025 M then we would want HCl to be 0.025 M. In this case, we have a 5:2 ratio so if the concentration of KMnO4 is approximately 0.025M then we need...
