Answer 1

Answer:

starch test....

In the presence of starch, iodine turns a blue/black colour. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test. For example, if iodine is added to a peeled potato or chewed rice or bread then it will turn black. Benedict's reagent can be used to test for glucose.

$\huge\boxed{\fcolorbox{red}{Pink}{Answer}}$

Test for carbohydrates

• To prepare a dilute solution of iodine, a few drops of tincture iodine are added to a test tube half-filled with water.

When the dilute solution of iodine is added to food items containing starch e.g., raw potato, the color of the food item changes to blue, indicating the presence of starch.

Let us perform a test to find the presence of starch in a food item :-

Take a raw potato and cut it into two halves. Put one half of the potato on a plate and use a dropper to put 2-3 drops of iodine solution on it.

You will observe that the color of the potato slice changes to blue-black.

The presence of this blue-black color indicates that potatoes contain starch.
