(dialysis tubing). The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration in the attempt to reach homeostasis in different circumstances. Introduction: The main purpose of this lab was to observe diffusion and osmosis. This is demonstrated using dialysis tubing and a combination of monosaccharaides‚ disaccharides‚ water (H20)‚ and sodium chlorine

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which
