Question 12:

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 on the socks. What can be the possible reason?


The saree of Paheli՚s teacher might have been starched. And starch turns blue black with iodine solution. Paheli՚s socks did not have starch on it thereby showing no change.

Question 13:

Paheli and Boojho peeled some potatoes and cut them into small pieces. They washed and boiled them in water. They threw away the excess water and fried them in oil adding salt and spices. Although the potato dish tasted very good, its nutrient value was less. Suggest a method of cooking potatoes that will not lower the nutrients in them.


Wash, peel, cut and cook the potatoes. Cooking in a small amount of water and then frying in a small quantity of oil conserves the nutrients.
