Hey I am really stuck for my Chem IA. I am doing vitamin c content in lemon juice and how it is affected by temperature and the thing is I have no idea how to calculate what the vitamin C content is in the juice. I have done the experiment whereby I titrated it all with an iodine solution and starch indicator and so on, I just don't know how to get the number which tells me what the vitamin c content is so I can compare between the heated samples. Right now all I have is some numbers saying how much iodine solution was needed to titrate it until a blue colour appeared, which does not really help. So if anyone knows please tell me!!!
Hey guys So I've been studying 8.2 and 8.3 (extremely complex and hard, might I add) and there is so much info. I just can't understand what to give importance to (IM using the Oxford book) DO I have to remember ALL diagrams, reactions structures? I understand how Calvin and Krebs work but do I have to remember each and every reaction in this cycle and remember the reduction, oxidation and everything else? Thanks!
