Which of the following tests is used for starch detection?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Iodine test.
The Iodine Test is used for starch detection. In this test, iodine solution (usually iodine dissolved in potassium iodide) is added to the substance being tested. If starch is present, the iodine interacts with the starch molecules, resulting in a blue-black color. This color change is a positive indication of the presence of starch. The iodine test is a simple and widely used method in laboratories and educational settings to identify starch in various samples.
