A 10.00 ml sample of saturated calcium iodate in 0.0100 M potassium iodate was then titrated against the standardized sodium thiosilfate. The initial volume reading was 0.22 ml. The final volume reading was 17.33 ml. Calculate the solubility product constant for a saturated solution of calcium iodate dissolved in 0.0100 M potassium iodate

In one trial of the standardization of a Na2S2O3 solution, a 10.00 mL volume of 5.00×10-3 M KIO3 is pipetted into a 250 mL Erlenmeyer flask. The solution is titratedto the endpoint with 15.23 mL of the Na2S2O3 solution. What is the molar concentration of this sodium thiosulfate solution?
Suppose that 10.00 mL of 0.0100 M IO3- solution requires 12.68 mL of the thiosulfate solution to be standardized. What is the molarity of the thiosulfate solution? Answer with a number with no unit.
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...
I am doing a titration lab using sodium thiosulfate pentahydrate to determine an amount if iodine. I'm having issues setting up the balanced equation to determine the mole ratio of iodine to thiosulfate. I used an approximate .080M solution of Sodium Thiosulfate and then titrated into a flask containing 25mL of KIO3, 20mL H2SO4 and 2g KI. Final mL of Sodium Thiosulfate used to complete titration was 37.36mL of Na2S2O3 5H20. I then did the same process for a 25mL...
A solution of sodium thiosulfate, Na2S2O3, is 0.7707 M. 7.42 mL of this solution reacts with 24.81 mL of I2 solution. What is the molarity of the I2 solution? 2(Na2S2O3) + I2↔Na2S4O6 + 2(NaI) 20.28 mL of the I2 solution from above is required to titrate a sample containing As2O3. Calculate the mass of As2O3 (197.8 g/mol) in the sample. As2O3 + 5(H2O) + 2I2 → 2(H3AsO4) + 4HI
