Titration report Purpose Vitamin C, Ascorbic acid, is one of the essential nutrients for human or animal body systems. Most animals can produce ascorbic acid inside the body by themselves but some animals like humans have to take ascorbic acid from outside of the body. We know ascorbic acid provides a lot of benefits inside of the body. Some the examples of the benefits are below; - It raises the immunity - It is cure for the common cold - It fixes tension and the grain of the skin - It makes the combination of the skin organization harder and stronger - It softens stress - It lowers a cholesterol level - It reduces aging affects, eye disease, skin wrinkling and cardiovascular diseases. For humans, the daily intake of ascorbic acid is between 70 to 90mg from foods like vegetables, fruits and juice. Normally, people eat vegetables boiled or baked. However, I don’t know if boiling changes the amount of ascorbic acid. Is it good for things to boil them a longer time? Therefore, the purpose of this investigation is to find out the impacts on ascorbic acid of high temperature, and length of time it is exposed to these temperature. I will use orange juice, which is high in ascorbic acid to investigate the experiment because it’s much easier and takes less time to do titration than using vegetables. I will use four significant figures because the accuracy of 10ml pipette is +-0.020. Materials and Equipment Solution Orange juice… I got this orange juice from the Warehouse in Blenheim on 4th of March, 2014 and experiment day was 18th of March,2014. I thought the time buying the juice for the experiment wouldn’t affect my result because I don’t have to calculate the original concentration of orange juice. I know it already from the label. Actually, there is a change in the amount of Vitamin C from 4th to 18th but I can’t know the date that they make it, how many days
