easyWhat do you think of Raman’s statement, All starches are carbohydrates. Class 6
Question 1.
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. Class 6
Answer:
If we test bean then it does not show blue-black colour in iodine, as it is a type of carbohydrate but not starchy.
Question 2.
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? Class 6
Answer:
Saree contains starch, likely used in the finishing process of the fabric. Starch reacts with iodine to produce a blue-black colour. On the other hand, her socks do not contain starch.
