What is the three steps in performing chemical test for sugar and starchand able to conduct these test?

Answer 1

For starch, we carry out the iodine test.

For this test, it's just adding a few drops of iodine solution to the solid on a white tile. If it turns blue-black, starch is present.

For sugar, if you mean reducing sugar, we carry out the Benedict's test.

Firstly, add 2cm^3 of Benedict's solution to 2cm^3 of glucose solution in a test tube and shake the mixture. Leave the test tube in a beaker of boiling water for 5 mins.

As for the control experiment, repeat step 1 using 2cm^3 of distilled water in place of glucose solution.

Answer 2

The three steps in performing a chemical test for sugar include 1) adding a few drops of Benedict's solution to the sample and heating it in a water bath, 2) observing the color change (from blue to green, yellow, orange, or red) if reducing sugars are present, and 3) comparing the color change to a reference chart. For starch, the steps involve 1) adding a few drops of iodine solution to the sample, 2) observing a color change to blue-black if starch is present, and 3) comparing the color change to a reference chart. Conduct these tests by following the steps mentioned using the appropriate reagents and samples in a laboratory setting.
