To detect starch, iodine can be applied directly to the tested materialGroup startsTrue or False

Describe the chemical test for starch.

odine tests for the presence of starch. Iodine is yellow, but turns blue/black when exposed to starch. You will add iodine to a tube of water (the test solution). If there is NOT starch in the test solution, what color should the solution be?Group of answer choicesBlue/blackYellowPink

10.State the colour iodine appears in the dimple plate if starch is still present.

Given below are the steps to be followed for performing starch test on a green leaf(i) Boil the leaf in alcohol(ii) Boil the leaf in water(iii) Dip the leaf in iodine solution(iv) Wash the leaf in waterThe correct sequences of steps are(i), (iv), (ii), (iii)(ii), (iv), (i), (iii)(ii), (i), (iv), (iii)(iv), (i), (ii), (iii)

Topic(s): The Speed Of A ReactionWhen solution A and solution B are mixed they react slowly to form iodine.Starch solution is added to the mixture to act as an indicator.When a certain amount of iodine is made there is a sudden colour change to blue-black.Plan an investigation to find the effect of temperature on the rate of the reaction between solution Aand solution BYou are provided with solution A, solution B. starch solution and common laboratory apparatus.
