Testing for the presence of starch is commonly done in Biology and food science to detect the presence of carbohydrates. Iodine solution is typically used for this test, as it turns blue-black in the presence of starch. This test can be useful in identifying starch in foods or in plant tissues.
the answer to tis would be iodine because it is uses in the method to test for presence of startch in a leaf
One common test for the presence of a -COCH3 group is the 2,4-dinitrophenylhydrazine (Brady's) test. In this test, the compound is treated with 2,4-dinitrophenylhydrazine in the presence of acid to form a yellow to orange precipitate, indicating the presence of a ketone or aldehyde functional group.
Yes, the biuret test will indicate the presence of peptides. If it turns violet, it is a positive result.
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
You can use iodine solution to test for the presence of starch in food. When iodine comes into contact with starch, it changes color from brown to blue-black.
Iodine solution!

to test for the presence of lipids.
Iodine turns blue-black in the presence of starch due to the formation of a complex between iodine and starch molecules.

In this test, the compound is treated with 2,4-dinitrophenylhydrazine in the presence of acid to form a yellow to orange precipitate, indicating the presence of a ketone or aldehyde functional group.
To test for the presence of bleach in water, one can use a simple chemical test kit that contains a reagent that changes color in the presence of bleach. This color change indicates the presence of bleach in the water sample.
To test for the presence of starch in cells.
yes potato has startch in it, like sugar in candy HAHA! :)
corn startch works better but it also depends on what you are cooking
what is used to test for the presence of salt in water
You can test for the presence of oxygen gas by using a glowing splint test. A glowing splint will reignite in the presence of oxygen. Alternatively, you can use a chemical reaction like the decomposition of hydrogen peroxide, which produces oxygen gas bubbles. Additionally, you can use an oxygen gas sensor to directly measure the presence of oxygen in the air.
