After standardizing your thiosulfate solution, you next mass and crush a tablet of vitamin C, which contains the active ingredient ascorbic acid. Next, you mix ~0.100-g of the crushed tablet with the components of the analyte solution (potassium iodate, iodide, and sulfuric acid). You then titrate the solution to the endpoint. Let's assume that the set up for this titration is identical to that of the standardization titration, except now you have added ascorbic acid to the analyte solution. Would you expect to deliver more/less/the same amount of titrant to reach the endpoint
