- Shana, a student in the Analytical Chemistry class, performed a Redox Titration to determine the content of hypochlorite ions (% w/w) in an unknown solution. First, Shana prepared a primary standard solution of KIO3 by dissolving 0.4791 g dry KIO3 in 250.00 mL DI water. Next, using the procedure in your lab manual, Shana used 50.00 mL of this primary standard solution to standardize the Na2S2O3 titrant, and 26.25 mL of titrant was consumed. Next, Shana prepared the unknown solution by diluting 12.8624 g of the solution in 250.00 mL of DI water. A 50.00 mL portion of this dilute unknown solution was titrated using the procedure in your lab manual, and 19.25 mL of Na2S2O3 solution was consumed. Answer the following questions about this titration. Recall the stoichiometry of the NET chemical equation for this reaction. Note: use appropriate significant figures in your answer! A. Calculate the concentration (M) of Na2S2O3 titrant. B. Determine the amount (g) of hypochlorite ion in 50.00 mL…What happens when a non-standard titrant is used in the titration of an unknown sample?a - The volume of the acid used will not be accurate.b - The normality of the acid used will not be accurate.c - The weight of the analyte will not be accurate.d - It will not matter.0.5 M of stock solution is given to be used for Titrant 1.
