CHEM 101L Chapter Notes - Chapter 6.5: Chemical Equation, Electronegativity, Salt Metathesis Reaction
Document Summary
Chem 101: precipitation reactions and introduction to the purification of. In the natural world, many resources come in mixtures. Within those mixtures are many things we have no use for and want to get rid of. If a metal is mixed in within carbon deposits or other organic deposits, it is called an ore. If a metal is mixed within other metals, it is called an alloy. In nature alloys are very common but they are used as is, but ores on the other hand contain compounds undesirable to us and so we must purify them into a more pure state. By purifying an ore we can get rid of the organic deposits that we don"t need and obtain the metal portions of the ore that we want to extract. The process is known as purification, but purification is one form of a precipitation reaction that has unique properties that gives it its name.
