Question 9.
Sugar is an example of carbohydrates. Sugar is tested with iodine solution but it does not change to blue-black colour. What can be a possible reason?
Answer:
All carbohydrates do not give blue-black colour with iodine solution. This is the only starch which gives blue-black colour with iodine solution. Though, sugar is a carbohydrate but it is not a starch. So it does not give blue-black colour with iodine solution.
Question 10.
What do you think of Raman’s statement, “All starches are carbohydrates but not all carbohydrates are starches.” Describe the design of an activity to test your answer.
Answer:
Carbohydrates are of many different types e.g., starch, glucose, fructose, maltose, sucrose, etc. So, we can say starch is a type of carbohydrate but other carbohydrates such as glucose, fructose, maltose, sucrose are not examples of starch.
We can do an activity to check whether a carbohydrate is a starch or not by using iodine solution. Only starch gives blue- black colour with iodine solution. No other carbohydrates give blue-black colour with iodine solution.
Question 11.
While using iodine in the laboratory, a few drops of iodine fell on Mishti’s socks and a few fell on her teacher’s saree. The drops of iodine on the saree turned blue-black while the colour on the socks did not change. What can be a possible reason?
Answer:
The possible reason for blue-black colour on teacher’s saree could be the presence of starch. The saree might have been starched. Mishti’s socks did not have starch on it, therefore the colour did not change.

Millets are small-sized grains which are very good for our health. They are rich sources of carbohydrates. Besides, they also provide us vitamins, minerals like iron and calcium, and dietary fibres. But they do not provide us proteins.
Question 13.
You are given a sample of a solution. How would you check the possibility of it being an iodine solution?
Answer:
We can check whether the given solution is iodine solution or not by adding a small amount of starch in it. If the solution on adding starch turns blue-black then the solution is iodine solution. If the solution does not turn blue-black then the solution is not iodine solution.
