    Bio IA about how cooking affects vit c concentration in brocoli
  2. Guys, I have to start my IA experiments ASAP and I decided to calculate the Vitamin C content in different stages of a Banana but I am struggling to figure out how to obtain the banana extract to test in the DCPIP solution or iodine Vitamin C test. I need a liquid extract and I could not figure out how to make the extract. Please help me THanks
  3. In this experiment I am supposed to count the concetration of vitamin C in tested sample. Vitamin C (ascorbic acid) has the formula C6H8O6, and can be oxidized to dehydroascorbic acid C6H6O6, using iodine. Oxidizer comes from potassium iodate and potassium iodide, which react with each other in presence of hydrochloric acid. KIO3 + 5KI +6HCl → 3I2 + 3H2O + 6KCl Iodine reacts with ascorbic acid as shown below: C6H8O6 + I2 → 2HI + C6H6O6 Due to this reaction, formed iodine is immediately reduced to iodide as long there is any ascorbic acid present. When ascorbic acid has ran out, the remai
  4. Design lab topic: temperature affecting vitamin c content in orange juice temperatures are 25°C, 35°C, 45°C and 55°C. I am going to be using starch to determine how much drops of iodine needed to oxidize it. Question is: will increasing the temperature affect the results (will it damage the starch n iodine content?) Thank you
