The Chemical Elements Part 1

Assalamu'alaikum..

Hi Everyone, long time no see.

Now, DS want to discuss about the Chemical Elements. but, DS will separate it into a few part. And for part one, there are Alkali metal group. DS hope you guys, get it, understand it, and enjoy the article


ALKALI METAL GROUP

1. PROPERTIES

                     Located
in the SPU goal IA, is not found in nature in a free state (highly reactive). Na
and K are common in nature as compounds, while others only a few. The elektronegative
of ionization energy and small, The larger the number the smaller the atomic
energy cohesion that is soft, strong reducing agents, dissolved in a solution
of ammonia, specific colored Bunsen flame. Storage in the petroleum /
hydrocarbon that is inert (avoid oxidation O2).



2. MAKING ALKALINE

                     By
reducing the oxide, or with elektrolisis of molten salt. Sodium is obtained by
the process of Down. Potassium is obtained by passing steam through the molten
sodium KCl.



3. USE ALKALINE

                    Alliance
Na / K: cooling atomic reactor, alliances Li / Pb: cable wrapping soft,
alliances Li / Al: enhancing corrosion resistance of aluminum, Rb and Cs to
form alliances with Na and K: photoelectric cells, and Na: reducing TiCl4 into
metal Ti.



4. Compounding ALKALINE

                     NaCl:
preservatives and manufacture of other compounds.  NaOH (caustic soda): manufacture of other
compounds, raw materials for soaps and detergents, in the paper industry, and
rayon fiber.  Na2CO3 (soda): in the glass industry, paper, detergent, for
metal protection and lower the water hardness. NaHCO3 (baking soda): in the
manufacture of bread, eliminating rancidity in butter, removing gum on silk,
remove wax and grease on fleece wool, and a mixture of firefighters.
