To 47.62 ml of wine were added 5 mL of concentrated KI solution and 32.11 mL of solution containing (0.7557 g KIO 3)/(100.00 mL solution). The wine+reagent mixture was acidified with 10 mL of 1 M HCI to create a known number of moles of I 2 by the reaction 10 3+ excessi+ some H*-> 31 2 Some of this I 2 immediately reacted with the sulfite in the wine sample by the reaction SO 3+12-> products we don't care about The left over I 2 was titrated to a starch end point with 10.14 mL of 0.04521 M thiosulfate solution, by the reaction 12+ 25 20 3-> products we don't care about What is the concentration of sulfite in the wine, expressed in mM?
