A tablet containing 500 mg of vitamin C was titrated with 20.15 ml of KIO3 to the end point. The same KIO3 was used to titrate 12.1 ml of a commercial juice blend. The juice required 2.40 ml of KIO3 to reach the end point. How many mg of Vitamin C are in the sample of juice blend?
To cakculate the amount of Vitamin C in the given sample following equation is derived
Average mL of titrant used for tablet = mL of titrant used for juice
500 mg of vitamin C in tablet ? mg vitamin C in Juice
? mg vitamin C in Juice = mL of titrant used for juice)(500 mg vitamin C in tablet)
Average mL of titrant used fpr tablet
mg vitamin C in Juice = (500 mg)(2.40)
20.15mL
mg vitamin C in Juice = 59.55 mg
The answer is 59.55 mg of vitamin C in the given juice.
