a) Starch is used as indicator ( dark blue color turn into colorless solution at end point)
b) 2S2O32- + I2
--> S4O62- +
2I-
2 mole of thiosulphate ion react with each mole of iodine
c) raction 2 IO3-
+Ca2+
Ca (IO3)2
When excess iodate is added the reaction move in forward direction and more Ca (IO3)2 will be formed

Vitamin C in a titration with potassium iodate
References Mailings Review View AaBbcode Abccdee AaBbcc No Spacing Heading 1 Normal 3. A suitable method for the determination of vitamin C (C.H.O.) is a titration with potassium iodate (KIO). Potassium iodate is used as a titrant and is added to an ascorbic acid solution that contains strong acid and potassium iodide (KI). Potassium iodate reacts with excess potassium iodide, liberating molecular iodine (12): [1] KIO, + 5KI + 6H 31, +6K...

Suppose the solubility product constant of calcium iodate is 6.47 x 10-6. If the concentration of calcium iodate is 0.45 M. What would be the concentrations of Ca2+ and IO3- at equilibrium? Would this solution form a precipitate? Is the solution unsaturated, saturated, or supersaturated? Note* Ksp = [Ca2+][IO3-]2

A 0.5g sample of cement is added to a flask and is placed in a hot water bath with ~20ml of ethylene glycol where it was mixed with a stir bar for 20 minutes. After 20 minute, the liquid was put through a vacuum filtration to collect the liquid. The filtrate was then transferred to another flask. To the filtrate, 3.00ml of 0.1M HCl was added. 50ml of 0.005M potassium iodate, and 0.5g of solid potassium iodide was also added...
