Question

Note that wording can be tricky sometimes. Suppose that the amount of ascorbic acid in the sample you are about to titrate is 96 mg. (this means 96mg in 1 25mL sample, do not divide by 10 to get 9.6mg per 25mL sample, thats incorrect )

Answer 1

To determine the concentration of ascorbic acid in a 100 mL sample of orange juice, you need to calculate the moles of iodine reacted with sodium thiosulfate, then convert the moles of I3- to grams of ascorbic acid.

Step-by-step explanation:

The question pertains to the concentration of ascorbic acid in a 100 mL sample of orange juice.

First, we need to calculate the moles of iodine (I2) reacted with sodium thiosulfate (Na2S2O3) by subtracting the moles of I2 reacting with Na2S2O3 from the total moles of I2.

Then, we convert the moles of I3- to grams of ascorbic acid in the 5.00-mL sample, which can be used to determine the concentration of ascorbic acid in mg/100 mL of orange juice.
