Hello friends, in today’s article we are going to tell you what are the applications of electrolytics, so if you want to know the applications of electrolysis, then definitely read this article completely. Website (iticourse.comWe keep giving any kind of information through ) so let’s start.
Following are the applications of electrolysis:
Therefore, the electrochemical equivalent of an element is mass of the element) is equal to the number of amperes in the electrolyte of that element. Electric current It is released from the current in 1 second. Its unit is kg / coulomb.
So z = Atomic Weight / Valency
Meaning of electrolysis?
galvanic isolation whom galvanic isolation) is a design technique used to isolate an electrical circuit to eliminate other currents.
1) Purification of Metals
The impure or mixed metals are purified by electrolysis. in this method mixed metal) is taken as the anode and the cathode as a thin strip of pure metal. In this, a solution of a mixed metal is made with a salt. When current is passed through this solution, the pure metal gets deposited at the cathode and the impurity gets deposited at the anode.
2) Manufacturing of Capacitor-
high capacitance capacitor) to make electrolysis (Electrical layer is created between two plates in a capacitor by electrolysis. Such capacitors are called electrolytic.
This method is cheap and popular in practice. By this method a fine layer of expensive metals is plated on cheaper metals.
on a variety of items Gold, Silver, Nickel, Chromium Flake (Gold, Silver, Nickel, Chromium Flake) is raised. Silver is made of gold, iron is made of copper, iron is coated with nickel and they are made shiny by snowing. The base cover of an electric iron is an iron, which is then coated with a nickel electrolysis method and then polished. Copper utensils and brass utensils are polished in this way. Emmersion rod is coated with chromium
The electroplating process is as follows
- Wash the object on which electroplating is to be done thoroughly as its surfaces should not be greasy and dirty.
- This object is immersed in the electrolyte by tying it to a wire as a negative (–) electrode.
- Electrolyte is prepared from salts suitable for the metal on which the coating is to be plated.
- The metal layer to be plated on the object is made anode (positive (+)) electrode.
- DC in the electrolyte as shown in the picture. Shunts supply through generator If generator is not available then DC through rectifier.
Due to this, the positive (+) ions of the metal are released from the electrolyte and settle on the object (cathode). The negative (– ) ions react with the metal to form salts of the metal. According to Faraday’s first law (m = zit), the thicker the layer, the longer the current passes through it. A low ampere current should pass in it, after which the electroplated object is polished and iced.
This method is mainly used for book printing. By preparing the full page of the book, the handwriting of the whole page can be changed by the simple method. compose) is done, then its print is taken from plaster of paris. Graphite powder or fine powder is sprinkled on this impression, due to which its surface becomes a conductor, then after washing it with copper sulphate (Nila Thota) fine iron powder is sprinkled on it.
In this, iron makes a thin layer on the print of the book by separating the copper of the electrolyte, now hang it by making a cathode (-) electrode in the electrolyte of copper sulphate. In this the anode (+) electrode is made of copper. DC. (direct current or direct current) A very thick layer of copper can be deposited in 1 hour by giving supply.
This layer of copper is separated by the impression of wax or plaster of paris. After this, this type of copper type is made by melting lead (lead) and the book is printed on the printing machine (printing press).
