Document Summary
Experiment 1: amount of vitamin c in orange juice. Vitamin c, or ascorbic acid, in 6 different types of orange juice. Vitamin c is a vital substance that must be present in our body so that we can carry out our daily functions. Vitamin c resists infections, performs metabolic processes and is involved in tissue replacement. This experiment compared vitamin c levels in a squeezed navel orange compared to multiple store-bought orange juices. Through the use of volumetric analysis and a starch indicator, iodine was used to titrate samples of orange juice until there was a significant colour change, signaling the endpoint of the titration. The samples contained an average of 20. 9 mg of vitamin c, suggesting that other types of orange juice may have higher amounts of vitamin c opposed to others. This experiment was conducted in order to determine and compare the amounts of. Qualitative observations of all sources of orange juice.
