Suppose a student diluted and titrated a bleach unknown exactly as described in the experimental procedure except only a single titration was performed which required 15.04 mL of 0.100 M Na2S2O3. The density of the original, undiluted bleach unknown was 1.028 g/mL 1. Calculate the number of moles of Na2S2O3 used in...

Suppose you need to standardize a sodium thiosulfate solution for a titration experiment. To do so, you will react it with a solution of iodine. You add a 1.00 mL aliquot of 0.0200 M KIO3 solution to a flask, followed by 3 mL of distilled water, 0.2 g of solid KI, and 1 mL H2SO4. You then titrate the solution with sodium thiosulfate solution in order to determine the exact concentration of Na2S2O3. The end point of the titration is...

QUESTION 6 The next five problems are calculational in nature. The initial problem statement in each case is similar but the numbers will be different. In several cases, you have more information than you need. Be sure to answer only the question asked in each case - don't get carried away. It is found in an attempt to determine the mass percentage of sodium hypochlorite that 14.81 mL of 0.19 M thiosulfate are required to reach the endpoint in the...

Using your average titre, you will determine the moles of ascorbic acid present in the sample that you titrated. If a 10.00 mL sample of a solution required 12.75 mL of 0.001273 M KIO3 to reach the visual endpoint how many moles of ascorbic acid were in the sample? Give your answer in mol to six decimal places. Do NOT include units in your answer.
