    Aluminium ore is called bauxite. Bauxite contains aluminium oxide, water, iron oxide and other impurities. The purified dry ore, called alumina, is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work, since the ions are not free to move in the solid state. Unfortunately, alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina dissolved in cryolite. Cryolite is sodium aluminium fluoride (Na3AlF6). A solution of alumina in cryolite melts at about 900 °C and electrolysis is done at about 950 °C.…

    What Is A Chemical Change

    A Chemical change is any change that results in the formation of a new chemical substance. It is something that everyone learns about in school, but never really tries to see it in the real world. We all know the basic examples; baking a cake, burning wood… etc. What about the examples that are happening around us. For example, the Statue of Liberty has been through a chemical change. It was first a dull brown color, and now it is a green color. That happened due to a chemical change.…

    The course begins with a qualitative survey of matter and its changes. We introduce a molecular view of matter. We build quantitative techniques in the next three sections, two of which are based upon the basic principle of conservation of mass, and one based on conservation of energy. In the final section, qualitative application of ideas about chemical stability allows us to predict and explain properties of some simple substances.…

    Water may contain several ions, namely anions and cations which are toxic to humans. Hardness is the scum on water surface from significant concentrations of calcium and magnesium ions. Total dissolved solids is the measure of dissolved solids that are ionic in water. Turbidity is the presence of suspended solids in water which reduces penetration of light, resulting in a decrease concentration of oxygen. Acidity is the concentration of hydrogen ions in the water body. A pH of 5.5-7.5 (meaning slightly basic water) is preferred in water supplies. Dissolved oxygen is the measure of oxygen dissolved in aqueous solution whilst biochemical oxygen demand is the measure of oxygen used by organisms. Both of these are monitored to prevent harm caused to bacteria and organisms.…
