Fisis properties of Sea Water

Sea water is a mixture of pure water 96.5% and 3.5% other materials such as salts, dissolved gases, organic materials and particles had dissolved. Physical properties of sea water main is determined by the 96.5% pure water.
1. Pure Water properties
Pure water when compared with other fluids (with the same composition), has a unique character and extraordinary (Uncommon). This is the result of the molecular structure of water (H2O), in which hydrogen atoms which carry a positive 1 charge and oxygen atoms that carry a negative 2 charge atoms form a molecule in such a way in which atomic charges are not ternetralisir as the angle formed between the two hydrogen atom is only 105o (neutral conditions will be formed if the angle formed is 180o). As a result, pure water has properties as follows:
1. Water molecules are electric dipoles, which form a collection of molecules (polymers) with an average of 6 molecules at a temperature of 20oC. Therefore, the water reacts more slowly (to change) rather than individual molecules.
2. Water has a separate power enormous, as a result of dissolved material will increase electrical conductivity of water. Pure water having electrical conductivity is relatively low, but the sea water has a conductivity of pure water and copper. At temperatures 20oC, the drag (resistance) 1.3 sea miles (with a salt content of 3.5%) comparable to the pure water 1 millimeter.
3. 105o angle close to the tetrahedral angle, ie the structure with 4 arms that come out of the central atom with a uniform angle (for 109o28 '). As a result, the oxygen atoms in the water trying to get the 4 hydrogen atoms in a tetrahedral arrangement. This is called a hydrogen bond (hydrogen bond) that require the binding energy of 10 to 100 times smaller than the bonds that water molecules are more flexible in reaction to changing chemical conditions.
4. Tetrahedron has a nature of a wider network than the molecular composition of the nearest collection. They form a collection of one, two, four and eight molecules. At high temperatures one set of molecules and two more dominant, while with decreasing temperature, cluster (cluster) is more great is to be dominant. Larger bunches fill a smaller space than the same number of molecules with smaller bunches. As a result, the density
