Sodium thiosulfate, Na2S203, is an important reagent for titrations. Its solutions can be standardizedby titrating the iodine released when a weighed amount of potassium hydrogen iodate, KH(IO3)2 (389.912g/mol), is allowed to react with excess potassium iodide in acidic solutions. The net ionic equations are:8.I0; + 51+ 6 H* → 3 I2 + 3 H2OI + 2 S20; → 21+ S406²production of iodine from KH(IO;)2:2-titration of iodine:What is the molarity of a sodium thiosulfate solution if 34.29 mL are required to titrate the iodine releasedfrom 0.1847 g of KH(IO3)2?

Molarity of a solution is defined as the moles of solute present in one litre of solution.

Answered: Sodium thiosulfate, Na2S2O3, is an…

You are asked to determine the percentage of the components of a mixture containing sodium iodide, NaI, magnesium hydroxide, Mg(OH)2, and barium sulfate, BaSO4. The total mass of your mixture sample is 4.82g. First you extracted the NaI from the mixture with water and filtered insoluble Mg(OH)2 and BaSO4 from the solution, containing the NaI. After evaporating and drying the filtrate, you find that you have recovered 0.95g of NaI. When you react the insoluble residue of Mg(OH)2 and BaSO4 with 3M HCl, the Mg(OH)2 dissolves. After decanting the supernatant liquid containing aqueous MgCl2 from the insoluble BaSO4 and drying the solid, you recover 2.04g of BaSO4. Finally you add 3M KOH solution to the aqueous solution to precipitate the Mg(OH)2. After filtering thesolution and drying the precipitate, you recovered 1.21g of Mg(OH)2. Calculate the percent Mg(OH)2 in the original sample mixture.
