Conversely, we might have a mixture of an acidic organic compound and a neutral compound to start out with. In that case, we would add a mineral base in the first place, to take a proton away from the acidic compound. The mineral base might be something like sodium hydroxide or sodium bicarbonate. In the drawing, it is just represented as Na + B-.

The lithosphere consists of rocks, which contain minerals. Minerals are natural compounds formed through geological processes. A mineral could be a pure element, but more often minerals are made up of many different elements combined. Minerals are useful chemical compounds for making new materials that we can use in our daily lives.

The Dana classification assigns a four-part number to a mineral species. Its class number is based on important compositional groups; the type gives the ratio of cations to anions in the mineral, and the last two numbers group minerals by structural similarity within a given type or class.

A compound results from a chemical reaction between components, forming a new substance. For example, you can combine iron filings with sulfur to form a mixture. All it takes is a magnet to separate the iron from the sulfur. On the other hand, if you heat the iron and sulfur, you form iron sulfide, which is a compound.

Aug 25, 2011 · There is no simple answer to this as it depends on the individual compound in each and every case. For example, you can get mercury and oxygen from mercury oxide just by heating. With water H2O you can get hydrogen and oxygen bb electrolysis. But if you want copper, Sulfur and oxygen from copper sulphate, it is much more difficult.

Compounds are groups of molecules with a definitive arrangement, and can only be separated by chemical means. Every mineral contains a defined ratio of specific molecules in its structure. For example, a water molecule is composed of H 2 O - two hydrogen atoms and one oxygen atom. When water molecules are grouped together, they form a body of

The compounds to be separated are treated with a mixture of a polar solvent (such as H 2 O) and a nonpolar solvent (such as CCl 4). The I 2 will dissolve in the CCl 4, while the KMnO 4 will dissolve in the H 2 O. By separating these two phases and allowing the solvents to evaporate, we can cleanly separate I 2 and KMnO 4.
