Photographers Use Sodium example essay topic

Sodium, a silvery white-metallic element classified under the alkali metals, has an atomic number of 11 and a mass of about 23 g. Sodium has been known since early times and was used by the people of Mesopotamia and Egypt to make glasses. Sodium is the sixth most common element found on the earth, usually not found in nature but more often in compounds such as salt (Na Cl). It's regularly found in compounds among dry lake beds, underground, and as well as in sea water in such places as: Belarus, China, France, Germany, India, Russia, Ukraine, United Kingdom, and the United States. Sodium conducts heat and electricity very easily.

Without this element life could not exist. Each compound is used for a certain reason. About 2.8% of the earth's crust contains this element making it the sixth most common in the earth's crust. It is an extremely chemically active element; if combined with water it tends to react vigorously. For example, since sodium is such a dangerous element it has to be handled with care and stored airtight meaning without oxygen. Sodium was first extracted into pure form in 1807 by an English chemist known as Sir Humphry Davy.

When it was first extracted into its pure form, he used the process of electrolysis where an electrical current is passed through a molten sodium compound such as sodium chloride. Many manufacturers today still use electricity to obtain sodium. Sodium is still highly manufactured for many industrial and commercial uses. It has commercial uses as well as industrial uses.

From soaps to fertilizers, sodium is used to make water softeners, textiles, and is also used to relieve stomach acid, sodium bicarbonate: a white crystalline weakly alkaline salt NaH CO 3 used especially in baking 1 powders, fire extinguishers, and medicine. Photographers use sodium: a hygroscopic crystalline salt Na 2 S 2 O 3 used especially as a fixing agent and a reducing or bleaching agent to fix photographic images on paper. Sodium in its pure form also has industrial uses such as in catalyst, which help in making synthetic rubber. Sodium is combined with other metals to produce titanium zirconium and many other chemicals. It is used in the manufacture of tetra ethyl lead and some power plants even use it in liquid form to cool nuclear reactors. Sodium fluoride is used to poison mice and roaches and also for ceramics.

Sodium is also put to use as a fertilizer, Chile salt pepper that is the compound sodium nitrate. Sodium is also a necessary element in the body for the maintenance of normal fluid balance and other psychological functions. Also, it is used in making vapor lamps. Finally after reviewing sodium's uses, we can conclude that sodium is a versatile element. Sodium and Potassium compounds are highly similar, so they can be substituted for each other.

Both are used in the industry but mostly sodium is used because it is less expensive. This secret was discovered in 1789 by a French chemist named Nicholas Leblanc, who was making soda (NaCO) with common table salt. Sodium is greatly useful and important and is used in many compounds. Some physical properties of sodium are melting point: 98 ^0 C, boiling point: 883 ^0 C, density: .

97 g / cm, atomic radius: 0.157 nm and it is a solid. In a conductivity test, sodium chloride turned out to a strong electrolyte in comparison with mercuric chloride solution which turned out to be a weak electrolyte: a compound that conducts an electric current in an aqueous solution or in the molten state. Sodium is produced when molten sodium chloride is electrolyzed. It is an alkali metal manufactured on a large scale. In order to make the metal sodium ions have to be reduced. After researching sodium's uses in everyday life I came to the conclusion that sodium is a necessity and should be used carefully.

It is an inexpensive and useful element that should not be played around with because it could cause a lot damage to anyone or anything. It can be used in various ways, so if sodium would not exist, life itself would be totally different. It is unbelievable that an element such as sodium can be very dangerous and at the same time.
