Explanation of Water as a Solvent for Life
Water is one of the most important ingredients in life. The hydrogen bonds will bind water molecules together until they fuse. When water is liquid, hydrogen bonds are so fragile that they are formed, separated and re-formed very quickly.
Water as a Solvent for Life
With the existence of hydrogen bonds can arrange water molecules so that it will have beneficial water properties. Some chemicals cannot form a solution, but are only dispersed in water.
Solution
the solution in this case is a mixture of two or more substances. Material that has dissolving properties is called a solvent. On the other hand, dissolved substances are called solutes. For example, one tablespoon of sugar is put into a glass filled with water, then the sugar will be dissolved in water. Sugar and water will become a uniform mixture of "homogeneous", sugar as a solute, while water as a solvent.
Another example is a solution of kitchen crystals that can also dissolve in water. Kitchen salt is an ionic sodium chloride "NaCI" compound, oxygen from negatively charged water molecules. The oxygen will bind to the sodium cation. Likewise, the chloride anion will attract positively charged hydrogen from water molecules. Water will penetrate the salt crystal and will eventually dissolve all the ions. The nature of water will separate sodium from chloride so that the two "sodium and chloride" solutes will be dissolved homogeneously in water.
Colloid
In this case, colloids are two or more substances whose mix is between homogeneous and heterogeneous. This is due to differences in particle size between the solute and the solvent. Colloidal particles cannot be seen on a regular microscope, but with an ultra microscope, examples of colloids are tomato mayonnaise sauce and milk clumping.
Suspension
Suspension is two substances which are mixed but heterogeneous, phase separation occurs between the solvent and the solute. This is also due to the large particle size of the solute compared to the platen, so the solute settles, for example starch in cold water.
From ancient times, chemists tried to find universal solvents that could dissolve all kinds of substances, but no one found a better solvent than water. Through the polarity of water molecules, water can be a versatile solvent for a particular substance based on particle size and relative surface area.
Mineral is a solid composed of chemical compounds that are formed naturally by inorganic events, which have regular atomic placement and have certain physical and physical properties.
The word mineral has many meanings, depending on what aspect we review it. Mineral in the sense of geology is a chemical substance or object which is composed of original or natural processes, has certain chemical and physical properties, and is usually solid. The original chemical compound is that minerals must be formed naturally by nature, because many substances that are the same nature as minerals can be made in the laboratory. Minerals are composed of atoms and molecules of different elements but have a regular pattern. Because of this regularity makes minerals have regular properties.
Mineralogy is a branch of geology that studies minerals, both in the form of individuals and in the form of unity, including learning about physical properties, chemical properties, how they are present, how they occur and how they are used. Minerology consists of the words mineral and logos, where the meaning of minerals has a different meaning and is even confused among the laity. Often interpreted as non-organic (inorganic) material. So a clear understanding of the mineral boundaries by some geologists needs to be known even though in reality there is not a single general agreement for the definition (Danisworo, 1994).
