Electrolysis of solutions

Electrolysis of acidified water

Water is a poor conductor of electricity, but it does contain some hydrogen ions, H+, and hydroxide ions, OH-. These ions are formed when a small proportion of water molecules naturally dissociate. If water is acidified with a little dilute sulfuric acid:

H+ ions are attracted to the cathode, gain electrons and form hydrogen gas

OH- ions are attracted to the anode, lose electrons and form oxygen gas

The overall balanced equation for the process is: 2H2O(l) → 2H2(g) + O2(g)

The volume of hydrogen given off is twice the volume of oxygen given off.

Electrolysis of dissolved ionic compounds

An electrolyte formed by dissolving an ionic compound contains:

hydrogen ions from the water and positive ions from the compound

hydroxide ions from the water and negative ions from the compound

The ions compete at each electrode to gain or lose electrons.

At the cathode

Whether hydrogen or a metal is produced at the cathode depends on the position of the metal in the metal reactivity series:

the metal will be produced if the metal is less reactive than hydrogen

hydrogen will be produced if the metal is more reactive than hydrogen

The relative reactivity of selected elements from most to least: potassium, sodium, calcium, magnesium, aluminium, carbon, zinc, iron, tin, lead, hydrogen, copper, silver, gold, platinum.

Example

Predict the product formed at the negative electrode during the electrolysis of sodium chloride solution.

Hydrogen will be produced because sodium is more reactive than hydrogen.

Photolytic decomposition is chemical reaction where photons are broken down and interacts with target molecules. Explanation: Photolytic decomposition is also known as photolysis. In this reaction the reactant molecule gets decomposed into two resultant molecules or products.
