Homogeneous Catalysis and Catalyst with Example
The main purpose of catalysis is to accelerate the chemical reaction process.Homogeneous catalysis is such a catalysis where the catalyst remains as in the same state as that of all the reactants involved in the chemical process-this is just opposite situation of heterogeneous catalysis process, where catalyst is in the different state from the reactants.
Homogeneous catalysis example-a typical example of homogeneous catalysis can be a solid catalyst with the reactants as either liquids of gasses.
Persulphate ions are extremely strong oxidizing agents and Iodines ions has the property of oxidized easily. Despite the mentioned fact when both the types of ions start reacting in water the reaction process is too slow.
S2O82 + 2I- ---------------------> 2SO42 -+ I2
To speed up the reaction process Iron(II) or Iron(III) are added to the same solution. For instance, when Iron(II) ions are added in the solution, by reacting with the persulphate ions Iron(II) becomes irons(III) and again when iron(III) reacts with Iodine ions then again comes back to its initial iron(II) state.

What is the oldest homogeneous catalyst- the oldest is metallo-engymes.
Natural homogeneous catalysis saving our life
In nature also, we find some good example of homogeneous catalysis e.g. every moment the creation and destruction of Ozone( O3) is taking place. This is happening by Oxygen molecules absorbing ultraviolet rays and splitting its own molecules into Oxygen ions. These Oxygen ions once again reacting with the ordinary oxygen molecules and creating Ozone molecules. This may sound like any normal chemical reaction-but it has extremely valuable significance for the survival of living creatures of this planet. By destructing and creating Ozone with the help of ultraviolet light, homogeneous catalysis process preventing the penetration of ultraviolet rays to our atmosphere, exposure to ultraviolet light can cause us many life threatening diseases.
