2013-09-30 · I was given a lab in class the other day, our main objective was to discover the percent concentration of hydrogen peroxide in the consumer product. We did a titration previously with KMNO4 and acidic Iron 2+, using our average from the buret reading to figure out our molarity of KMNO4. In the second equation 10 ml of diluted hydrogen peroxide (diluted from 25 ml out of 1.00 L, being diluted
