week 9 : measure resistance of sugar in mineral water

objective: to measure resistance sugar in mineral water. During the experiment, the resistance value can be observe.

Steps:

1. one cup of mineral water.
2. put 1 teaspoon of sugar in the cup and stir it well then measure the resistance.
3. repeat step 2 until 5 teaspoon of sugar been measure.

Result: the resistance value increase when each spoon of sugar been pour in the mineral water.

conclusion : from the experiment, sugar dissolves in water because when a sucrose molecule breaks from the sugar crystal, it is immediately surroundedby water molecules. The sucrose has hydroxyl groups that have a slight negativecharge. The positive charge of the oxygen found in the water molecule bindswith the sugar. As the hydration shell forms around the sucrose molecule.
