Dr. waters found an old bottle of dilute hydrogen peroxide in her refrigerator and needs your in determining the percent hydrogen peroxide that still may be present. she knows that by keeping the hydrogen peroxide cold and in the dark that it will have a longer shelf-life. but she has moved several times and does not know how old the dilute hydrogen peroxide is that remains. we are providing you with a standardized solution of potassium permangangate of 0.1057 m that you will use in the buret as the titrant. you will use a 20.00 ml sample of that old dilute hydrogen peroxide and determine the percent by mass. the beginning volume in the buret was 0.75 ml and the final volume to be 29.79 ml which allowed a faint pink color to persist for 30 s.
