When was the process of anodising first used for industrial purposes?
Anodising is a electrolytic passivation process, used on metals to increase corrosion resistance and for better adhesion of paint. It was first used for industrial purposes in 1923, to protect seaplane parts from corrosion.
Electropolishing is a process that removes what?
Electropolishing is a process that removes some type of material from a metallic workpiece. Basically, it is used to polish something. The term electropolishing is also known as electrolytic polishing or electrochemical polishing.
What is the purpose of the pieces of porous pot?
Porous pots are used in electrolytic cells to separate the two half-cells while allowing ion flow between them. This helps prevent mixing of the electrolytes and enables the cell to function properly. It also helps maintain the concentration gradients needed for the electrolytic process.
Is bauxite turned into alumina?
Yes, bauxite is turned into alumina through a process called the Bayer process. In this process, bauxite is crushed and mixed with sodium hydroxide to produce alumina. Alumina is the main component used to produce aluminum metal.
Where does reactions occur in a electrolytic cell?
In an electrolytic cell
What is electrolytic reduction?
Electrolytic reduction is a process where a chemical compound is reduced (gains electrons) using electricity as the driving force. This occurs at the cathode of an electrolytic cell when a voltage is applied, causing a reaction to take place. This method is often used for extracting metals from their ores.
What is meant by electrothermal formulation?
formation of thermal energy

What is the material used in electrolytic capacitor?
Alluminium
What type of capacitor is used in fan?
electrolytic
Why should electrolytic capacitors not to be used in AC circuits?
Electrolytic caps are polorized and are used for filtering and will charge up to a DC value as in power supplies.
How would you explain electrolytic refining?
The process of purifying metal ingots which are suspended as anodes in an electrolytic bath, alternated with refined sheets of the same metal, which act as cathodes.
Which type of batteries used in inverter?
electrolytic battery

Which American developed electrolytic process for manufacturing Aluminium?
Martin Charles Hall in 1886

What is the difference between electrolytic reduction and electrolytic refining under these heads a. electrodes b. electrolytes c. reaction at positive and negative electrodes?
The difference between electrolytic refining and electrolytic reduction is as follows: a. In electrolytic reduction graphite electrodes are used which are of same size. in electrolytic refining the anode is made of the impure metal which is to be purified and the cathode is made from that pure metal. initially the cathode is thick and the anode is very thin. b. the electrolyte used in electrolytic refining is the metal sulphate with acid (acid id added to increase the conductivity) which is aqueous in nature. whereas in electrolytic reduction molten chloride form of the solution is used. c. The impure metal at the anode displaces the metal from the aqueous solution and the these ions go to the cathode and attach to the cathode as they are now pure. basically the impure metal at the anode directly doesn't go to the cathode, its a indirect process. as the reaction goes on, the size of the anode reduces and finally disappears and the cathode becomes thick as all the impure metal is converted into pure metal. this happens in electrolytic refining. whereas in electrolytic reduction the metal from the molten solution deposits on the cathode and chlorine gas is evolved at the anode. general differences: a. in electrolytic reduction no anode mud is formed and in electrolytic refining anode mud is formed from the impurities oh the impure metal. b. electrolytic reduction is done to extract metals of high reactivity from their ores. electrlolytic refining is done to purify (refine) metals from their impure form.
