Question

The rate of the iodine clock reaction below is measured by the time required for a color to appear. Any iodine made by the first reaction is rapidly consumed by the second reaction. The color of iodine only appears when thiosulfate is not present in the mixture. That color is blue when starch is present and brown otherwise. Label each reaction mixture below with the appropriate color. lodide, persulfate, and thiosulfate are mixed (no starch is added), and thiosulfate is completely consumed lodide, persulfate, thiosulfate, and starch are mixed, and thiosulfate is partially consumed lodide, persulfate, and starch are mixed (no thiosulfate is added) lodide, persulfate, thiosulfate, and starch are mixed, and thiosulfate is completely consumed lodide, persulfate, and thiosulfate are mixed (no starch is added), and thiosulfate is partially consumed blue clear brown

Explanation / Answer

1) The Color become colour less,so the solution become clear after completely consumed and there no starch solutions.

2) In that case thiosulfate partially consumed and starch Solutions present,so the Color become blue.

3)There are no thiosulfate present and starch solutions mixed so the Color become blue.

4) thiosulfate completely consumed and also starch present,so the solution become colour less.

5) thiosulfate partially consumed and there are no starch solutions, so the colour become brown.
