Question

Carbohydrates can be tested by using a) iodine solution. b) caustic soda c) copper sulphate.​

Answer 1

Answer:

carbohydrates can be tested by using caustic soda.

Answer 2

Carbohydrates can be tested using an iodine solution. (Option a)

• Carbohydrates include nutrients such as fibers, sugars, and starches.
• Monosaccharides, disaccharides, and oligosaccharides are simple carbohydrates (Saccharides are sugars).
• The iodine test is the common test done to confirm the presence of starch.
• The iodine solution is brown in color.
• In the presence of starch, it turns blue-black.
• Depending on the length of the glucose chains in the saccharides, the intensity of the blue color varies.
• Thus, this test can help distinguish the saccharides from each other.
