Abstract Literature on Van’t Hoff’s law states that water potentials and zero weight change osmolalities will be the same for potato cores placed in varying concentrations of solutes of NaCl‚ glucose‚ and sucrose. This experiment was designed to test these predictions and compare them to data gathered course wide. We found that the mean water potentials were all within 0.26 bars of each other‚ and that the zero weight change osmolalities were all within 0.035 mols of each other. This supported Van’t

IODINE TEST FOR STARCH The Iodine test is used to test for the presence of starch. Iodine solution — iodine dissolved in an aqueous solution of potassium iodide — reacts with the starch producing a purple black color. The colour can be detected visually with concentrations of iodine as low as 0.00002M at 20°C.
