A 0.1358-g portion of potassium iodate (MW 214.00), about 2 g of potassium
iodide, and 2 mL of 6 M hydrochloric acid were dissolved in 25 mL of distilled
water. The triiodide formed during the ensuring reaction was titrated to the
starch end point with 31.94 mL of a thiosulfate solution. A 25.00-mL triiodide
sample solution was titrated to the end point with 21.33 mL of the standardized
thiosulfate solution. Calculate the concentrations of the thiosulfate solution and
the triiodide solution.

The iodine clock reaction involves reacting an aqueous solution of potassium iodate with another solution containing sulfuric acid, sodium bisulfite, and starch. The reaction begins colourless but at a certain point the free triiodide concentration builds up, complexing with the starch molecules and producing a dark blue to almost black colour almost instantaneously. Which of the following options will cause the blue colour to appear faster? Increasing pH Increasing bisulfite concentration Increasing starch concentration Decreasing temperature Increasing temperature
