Answer to Question #186761 in General Chemistry for Kyle

Question

For hypochlorite determination in bleach samples, the substance of interest is measured by titration with sodium thiosulfate (na2s2o3). the titrant is first standardized using 0.1075 gram potassium iodate (kio3) in an acidic solution requiring 30.25 ml of sodium thiosulfate titrant. the standardization follows the reactions given below.

 

(A) Calculate the standardized molar concentration of sodium thiosulfate, Na2S2O3? Write answer in THREE SIGNIFICANT FIGURES. Write the full computation of your solution.
