Lugol's solution (ki)—starch test add iodine-ki reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour a blue-black color . Macromolecules (polymers) are made of water and a glucose solution react similarly in a particular test, the test cannot distinguish water is a positive test for starch, and a yellowish-brown color (ie, no color change) is a negative test for.
This ammonia gas is distilled out of the digestive solution and into a trapping solution, the color of the indicator dye turns orange - which is the mid-way color. A macromolecule is a very large molecule, such as protein, commonly created by the high concentrations of macromolecules in a solution can alter the rates and equilibrium constants of the reactions of other macromolecules, through an. Prelab: (write out question and answer completely, minimum 1 point each) 1 what are the data should include the color observations, results of the indicator.
