Process by which ions in an electrolyte

What is Electrolysis?
How to Manipulate Electrolysis
We first need to make sure what sort of solution we shall
use, will it be molten, aqueous, dilute or concentrated.
Next we shall inquire upon which gas or metal do we need
to extract out of the process.

How to get Hydrogen
From a electrolytic cell
The methods…
There are many methods to get
Hydrogen out of electrolytic
cells

There are many more, but these
are the more common methods

Water Electrolysis
The most common method of
obtaining hydrogen from
electrolytic cells is through
the electrolysis of water. In
this process, water is split
into its constituent elements,
hydrogen and oxygen, using an
electric current. The hydrogen
gas is then collected at the
cathode, while oxygen gas is
collected at the anode.

Alkalineolysis
In this method, a solution of potassium hydroxide or sodium
hydroxide is used as the electrolyte instead of pure water.
This makes the process more efficient as the hydroxide ions
in the solution help to conduct the electric current.

Sulfuric Acid Electrolysis
In this method, we use DILUTE
sulfuric acid, this acid has 3
ions, they are H+, OH-, SO42- the
anode receives OH- making
oxygen gas, and the CATHODE
makes a wonderfully flammable
HYDROGEN gas.
