Question

Why does hydrogen go to the negative electrode?

Answer 1

Hydrogen:

1. The lightest component is hydrogen. Beneath ordinary circumstances, hydrogen may be a gas composed of diatomic particles with the equation $H_2.$
2. It's colourless, odourless, tasteless, non-toxic, and greatly combustible. Hydrogen is the foremost inexhaustible chemical component within the universe, bookkeeping for around 75% of all conventional stuff.

Reason for hydrogen going to the negative electrode:

1. When an aqueous solution is electrolyzed using inert electrodes, the ions released are determined by the relative reactivity of the elements involved.
2. If the metal is more reactive than hydrogen, hydrogen is created at the negative electrode (cathode).
3. Unless the solution contains halide ions when the halogen is created, oxygen is formed at the positive electrode (anode).
4. This occurs because water molecules in the aqueous solution break down, releasing hydrogen ions and hydroxide ions.
5. Electrolysis of aqueous solutions with inert electrodes is being investigated.
6. When water is exposed to an electric current, it undergoes the process of electrolysis, which breaks it down into oxygen and hydrogen gas. When an electric current is sent across a water molecule, it breaks down into the ions H+ and OH-.
