Suppose that you titrate a 3 g sample of orange juice and it turns out to contain only 95.5mg of vitamin C. Further, it took 32.45mL of DCP solution to reach the end point of the titration. Next, you boil a 3 g sample of orange juice for 15min and then titrate it, with the end point occurring after only 6.50mL of DCP solution is added. What percentage of the vitamin C was destroyed in the boiling?
