How does an electrolytic cell work simple answer?
An electrolytic cell uses an external power source to drive a non-spontaneous chemical reaction. Electricity is used to force electrons through the cell, causing a redox reaction to occur at the electrodes. This allows for the production of new chemical compounds or the separation of substances.
An electrolytic cell is made with zinc and aluminum electrodes Which of the following happen at the cathode of this cell?
At the cathode of the electrolytic cell with zinc and aluminum electrodes, the reduction of aluminum ions into aluminum metal will occur. Aluminum ions gain electrons to form solid aluminum metal, while zinc remains unchanged as it does not participate in the reaction at the cathode.
What are electrodes made of?
It varies. Electrodes can be made of iron, carbon, platinum or any number of electrical conductors.
Why do you think it is advantageous to use inert electrodes in the electrolysis processes?
If the electrodes are not inert, then they are going to become part of the chemical reaction, rather than just being conduits for electricity, and if they become part of the chemical reaction, they are going to get used up, and you will wind up with no electrodes.
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.
what do we call the chemical reaction that uses an electrical current to decompose a compound?
electrolytic decomposition reaction.

What is electrolytic decomposition reaction?
a chemical decomposition reaction produced by passing an electric current through a solution containing ions is known as electrolytic decomposition reaction

How can a galvanic cell become an electrolytic?
the redox reaction is reserved

electrolytic decomposition reaction.
An electrolytic cell is different from a voltaic cell because in an electrolytic cell?
In an electrolytic cell, an external power source is needed to drive a non-spontaneous redox reaction, while in a voltaic cell, the redox reaction is spontaneous and generates electric energy. In an electrolytic cell, the anode is positive and the cathode is negative, whereas in a voltaic cell, the anode is negative and the cathode is positive.
