Chemical Process Using Electric Current

Chemical process using electric current commonly called as electrochemical, but for general people this name may don’t familiar. Named by Electrochemical because on the process involved the chemicals and electrical, so the whole process called as electrochemical.

Electrochemical is not just happened in plant or industry or laboratory, this process also always happened in nature. This process can go and trigger by any different voltage surround the chemicals substance. The different voltage on the environment of certain substance can

cause the reaction happened. For example the process of corrode, because of any voltage different make iron that stick to copper can be corroded faster than other metal that don’t stacked to copper metal. This condition used to happen on Air Conditioner tubing. Other metal in AC corroded faster than other iron on other product. Now this condition have been avoided by replace the metal with plastic material.

On the process of electrochemical there is oxidation and reduction reaction because of different voltage or make different voltage. Scientist then uses this characteristic to create Automobile Battery and other process that use this characteristic. On charging process people use electric that use the reverse process of using battery.

Electrochemical also use on producing chemicals because by this process for some substances can separate compound into substances. The example of this electrochemical process is as on water electrolysis.

Reaction: H₂O ===> H₂ (gas) + O₂ (gas)

Electrochemical also can make the metal dissolved in the chemical solution vastly, and on the solution named by ion. This ion then go metal that have reverse voltage and stacked to them. This characteristic of metal ion being used in Electroplating Process. Metal will stick on the surface of other metal.

Removing Iron Rust Using Electrochemical Process

One way to remove iron rust is by electrochemical process. The iron or metal that will be rusted is given a negative charge and the other electrode means that it is positively charged, so the rust will be released from the metal because negative ions will come out of the metal and go to the positive electrode. If the process is continued, the iron may become shiny, not because it is coated in therapy because the surface is partly faded. This is because the iron functions as a negative electrode, where the ions on the surface of the iron will decay and dissolve into the chemical solution. To give an idea of this process, see the following video:

Sodium Sulfite and Sodium Hydrosulfite

Sodium Sulfite Sodium sulfite is a compound that is very easily oxidized. For this reason, it is employed in many cases where a gentle reducing agent is desired, e.g. to bleach wool and silk, as an antichlor after the bleaching of yarns, textile and paper, as a preservative for foodstuffs, and to prevent raw sugar solution from colouring upon evaporation. It is very widely used in the preparation of photographic developer to prevent from oxidation from hydroquinone and other agents. It has a small application in the field of medicine as an antiseptic and as an antizymotic for internal use. About 60% of the total merchant market is in the paper Industries. While merchant capacity is about 145,000 t/year, the paper mills have twice capacity to captive use. The demand for boiler feed water treatment is about 15%. It is use to remove oxygen from water and thus help to prevent corrosion and scale formation. These were four major production in 1891, one of which provided 50% percent of the

Viscose Fiber Production Process

Viscose fiber is a base material for textile industry. The first production of this kind product is in Indian than spread over the Europe and United States also in South Asia Country like in Indonesia. Viscose fiber is produced to anticipate the shortage of natural yarn for raw material to produce yarn in textile industries, beside synthetic yarn as replace natural cotton to produce fabric. This one is a simple drawing of viscose fiber production process . Viscose fiber is used to substitute the using of cotton as raw material for textile industry. Beside of cotton availability will not enough to supply market demand in the future, also cotton just available on harvesting season. If people just depend on cotton to produce textile then people will shortage of raw material to produce textile. Using viscose fiber to fulfill of textile industry will not any shortage raw material, beside the price is lower than cotton, viscose fiber also have better quality compare with synthetic fiber fo
