Starch is tested with the solution called Iodine. If starch is present when Iodine is dropped in, the solution will turn a brown, black color.
because there is starch in the food you tested
due to the presence of starch.
Bendedict's solution is a blue solution, when glucose is present, a brick-red precipitate is formed. If starch is present, the iodine solution will turn from yellowish-brom to blueish-black.
the iodine stayed orange because the starch wasn't present
It depends if it is starch, yes. Other sugar, NO!
The Iodine test uses Iodine solution, which is usually a brown colour. It is used to test for the presence of Starch. Iodine solution, iodine dissolved in an aqueous solution of potassium iodide, reacts with starch producing a blue black color. If the sample being tested doesn't turn blue-black, then starch isn't present.
1. Starch is used by plants.....and glycogen is animal food.... 2. Starch gives blue colour on testing with iodine solution. and glycogen gives red colour when tested wiht iodine solution. Thank you
polysaccharides and simple sugar
The presence of starch can be tested with the help of Iodine. Similarly Benedict's test solution is also used to detect the presence of starch.
no, because during a lab in science class, we tested it and part of it dissolved in the ethanol.
