I have been diluting the orange juice with distilled water and acetic acid then titrating this dilution with DCPIP. The only thing is I am unsure of why I am using acetic acid. What does this do to the vitamin C? Why is it necessary for this titration? Can anyone help??

Obviously you are not going to use strong acids like hydrochloric acid for obvious reason. _________________ ₪ [size=75]Blog[/size] ₪ Back to top Vicki Lacey Posted: Wed Jun 18, 2008 2:42 am    Post subject: Forum Freshman Joined: 17 Jun 2008 Posts: 2 Thank you Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First     Page 1 of 1 Science Forum Forum Index » Biology » Vitamin C experiment Jump to: Select a forum Natural Sciences----------------Astronomy & CosmologyBiologyChemistryEarth SciencesMathematicsPhysics People----------------Behavioral & Social SciencesHealth & MedicinePhilosophical DiscussionHistoryReligionPoliticsCriminology and Forensic Science General Technology----------------Computer ScienceElectronicsMilitary Technology Information Technology----------------Business & EconomicsEducationEngineering & Transportation International Issues----------------Environmental IssuesIn the News The Science Forum----------------General DiscussionIntroductionsScience-Fiction and Non-FictionExperimentationPseudoscienceLinksArt and Culture Site Administration----------------Site FeedbackTrash Can  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum
