notm Posted February 16, 2016 Report Share Posted February 16, 2016 my IA was on the effect of temperature on ascorbic acid/vitamin C and I'm trying to find the molarity of vitamin C in each trial. I used 20 mL of orange juice (which contains all of the vitamin c), 150 mL of water, and 1 mL of indicator. on top of that I titrated in an iodine solution whose volume varied depending on the trial. I have the # of moles of vitamin C in each trial, but for the liters of solution in the molarity calculation, would I use the 20mL orange juice, or OJ+water, or OJ+water+iodine solution? hope this makes sense!!

kw0573 Posted February 16, 2016 Report Share Posted February 16, 2016 if I understood the reaction correctly, use stoichiometry to find moles of vitamin C reacted and divide by original volume for original concentration Reply Link to post Share on other sites More sharing options...
