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.

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

Which test solution requires heat to trigger a reaction? (meaning, there will be no change in color UNLESS you add heat)Group of answer choicesStarch (Iodine)Sugar (Benedict's solution)Salt (silver nitrate)

Based on your pre-lab calculation (see lab manual), what is the threshold concentration of iodine required for the solution to turn blue?Question 9Answer2.50 × 10–3 mol/L2.00 × 10–5 mol/L5.00 × 10–3 mol/L4.00 × 10–5 mol/L1.25 × 10–3 mol/L

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)
