Glucose is a simple sugar that many organisms need to generate energy for themselves. The color change happened because the iodine reacted with the starch and formed a dark blue starch/iodine complex. The addition of water dilutes the starch solution and attempts to balance the concentrations on the both side of the cell membrane. EXPERIMENT PROCEDURE: 1) 250 ml of tap water was added to a beaker.
The effect of starch concentration on the gelatinization and liquefaction of corn starch. A specific chemical test or reaction is used to test for the presence of starch in foods or other items. If you heat up the reaction mixture, the blue color will disappear as the amylose coil structure will break apart at higher temperatures. The plastic baggie was permeable to the iodine.
The temperature||The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly|. Glucose test strips.
