ION
Ion is an atom or molecule by the number of
electrons are more or less thannormally, which gave it a positive or negative electrical
charge. Because ion "want" to beneutral by acquiring or losing electrons
berlebiha, it has chemical propertiesof interest. Ions normally present in solution. There are three
types of ions: anionsnegatively
charged, positively charged cations and radicals or radical ions are
veryreactive because it has a large number of free
electrons.Ion
solution is usually formed when certain molecules such as salts
dissolved in water.The
interaction between the solute and solvent molecules separating the
weak molecular bonds,such as salt, into two or more
ions. When
you put salt in the water, heinto sodium and chloride ions, which are both very important
for human life.If someone
shortage of salt for too long, they will eventually die. Ions are importantfor other life (called
electrolytes) is a potassium (K), calcium (Ca2), magnesium (Mg 2),hydrogen phosphate (HPO42-), and hydrogen carbonate (HCO3-).Ion
solution other than the salt solution is acidic and alkaline. For example
hydrochloric acid formedwhen hydrogen chloride dissolves in
water. Chloride is split into two hydrogen ions, H and Cl-.H reacts with water to
produce H3O, hydronium ions, while the chlorine remains aschloride ions. Because the
ionization process is complete, a strong acid called hydrochloric acid. Acid strengthmeasured by how much they have H
ions. Hydrochloric
acid has many H ions,so
he is very acidic. In fact, hydrochloric acid can
be dissolved through the glass and all metalsexcept
iridium, although the pace is slow corrosion.Another category of
ion solution is alkaline. But measured by the concentration of hydrogen
ions,ion concentration was measured by alkaline
hydroxide (OH-). One example of a base ispotassium hydroxide, which is a precursor chemical in most
liquid soaps are gentle.When dissolved in water, potassium hydroxide produces a strong
alkaline solution. Alkaliis a kind of base. Potassium hydroxide has a number of interesting chemical
properties - oneonly
is its hygroscopic (attracts water), which makes it a dryeris strong. When it reacts with water, the reaction is exothermic
which means generatingsignificant
heat.The last major group of ions are
radical ions or radicals. Examples
include radicalsuperoxide (O2-),
which is used by the immune system to killmicroorganisms that attack, and nitric oxide,
which used the body as a molecularan important signal. Such as acids and bases, radicals are very reactive
and has a number of applicationsin chemistry. One aspect
that is not good is that the existence of radicalin the body tends to break down the body's
tissues from time to time, causingof
aging.2 / 2
