CBSE Class 12 Chemistry Notes: Electrochemistry – Introduction
Electrolysis
In eletrolysis electrical energy is transformed into chemical energy.
When an electric charge is passed through chemicals having ions mostly in solution or molten state it results into addition reduction which consequently deposit or liberate chemical ions at electrdes.
One mole of e- holds a charge of approximately 96500 coloumbs which is shortly called as 1 Faraday charge.
When 1 Faraday charge is applied to a chemical substance it result into change of 1 equivalent of that specific chemical substance.
1 Faraday charge unit is very large for experimental purpose, thus sometimes chemist study by 1 coloumb of charge this is then known as to create an effect on 1 electro chemical equivalent.
Redox Cathode (Reduction) Auode (acidic)
Na+ + e- → Na Cl → e-
Na+ + e- → Na
Na+ + e- → Na Cl + Cl → Cl2

CBSE Class 12 Chemistry Notes: Electrochemistry – Photochemical Decomposition of Water
Conversion of solar energy into chemical energy can also be achieved by photochemical reactions, occurring in a homogeneous or a heterogeneous system.
Photochemical decomposition of water into H2and O2 is an interesting process.
H2O(l) →H2(g) + ½ O2(g) ∆ G o298 = 238 kJ mol–1
This reaction requires a photosensitizes because water itself does not absorb radiation above 200 nm. Generally, transition metal complexes exhibiting photoredox properties are used as photosensitizers for this reaction.
The main problem however, is that most transition metal complexes involve one electron transfer per photon absorbed, whereas the water spliting reaction,such as,
H2O(l) + 2e– → 2OH–(aq) + H2(g)
2H2O (l) → 4H+ (aq) +O2 (g) + 4e–
involve more than one electron. Ru(bipy)32+ (ruthenium bipyridyl complex ion), is a good photo-sensitizer, and acts as a reducing and oxidizing agent in the excited state. Reductive quenching of Ru(bipy)32+ produces a powerful reductant, Ru(bipy)3+ and oxidative quenching generates a strong oxidant, Ru(bipy)33+.
