Question

While using iodine in the laboratory, some drops of iodine fell on Paheli’s socks and some fell on her teacher’s saree. The drops of iodine on the saree turned blue black while their colour did not change onthe socks. What can be the possible reason ?

Answer 1

Answer:

The drops of iodine are used to detect the presence of starch in the food items. The possible reason for the colour change of saree is due to the presence of starch because strach is used to polish the saree. Paheli’s socks did not have starch on it, thereby their colour did not change.
