Hi, in this question it is given that aluminum metal can be produced by electrolysis of molten aluminum oxide, that is al2 .03.
00:12
We are asked to give the species at anode and cathode.
00:15
We know that at anode oxidation takes place, whereas at cathode reduction takes place.
00:26
Therefore, we can say that we are having al2 -o -3.
00:32
The ions which are present in this are al3 plus, which are 2 in number, and 02 -minus, which are 3 in number.
00:45
Therefore, we can write the reaction first at cathode.
00:49
Since reduction takes place, therefore we will take al -3 plus species, when it combined with 3 electron, there will be formation of aluminum, solid metal.
01:03
Al3 plus is present in aqua -state...
