EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce

The Biological Structure of Water Water is a substance with the chemical formula H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. Its structure enables it to carry out many important functions in the body. Water molecules are charged‚ with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. These opposite charges attract each other‚ forming hydrogen bonds. These are weak‚ long distance bonds that are very common and

Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results in a polar bond. If the atoms have a similar or close to similar amounts of electronegativity

WATER RESOURCES What are water resources? Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural‚ industrial‚ household‚ recreational and environmental activities. Virtually all of these human uses require fresh water. Only 2.7% of water on the Earth is fresh water‚ and over two thirds of this is frozen in glaciers and polar ice caps‚ leaving only
