Hi, now we will discuss about oxidation of plastics.
00:04
Plastics are polymers.
00:08
These are polymers which contain carbon and hydrogen.
00:14
Oxidation of plastics.
00:16
The oxidation of polymers, that means the oxidation of plastics, which contain carbon and hydrogen, that is hydrocarbon.
00:27
We know that hydrocarbons upon oxidation, this is said to be combustion reaction.
00:32
Burning of the hydrocarbon in presence of air in presence of oxygen is said to be combustion and the products of the combustion for the hydrocarbon are carbon dioxide and water as we don't know the number of the carbon atoms and hydrogen atoms just we have taken this is a general polymer it is a plastic it is a general polymer x -h -y upon oxidation it gives rise to carbon dioxide and water it is a general polymer it is a plastic it is a general polymer.
01:02
It is a general polymer.
01:02
It is a is a spontaneous process it is a spontaneous process spontaneous process means it takes place by itself without any influence means it is naturally occurring process burning of the plastic is the naturally occurring process and it takes place quickly so as it is a spontaneous process the plastic should not persist in the environment even though the spontaneous reaction oxidation of plastics is a spontaneous reaction but the plastics or the plastic materials tend to persist in the environment what is the reason we have to explain even though the reaction is spontaneous reaction the oxidation of the plastic is a spontaneous reaction but the plastics tend to persist in the environment we know that in nature some spontaneous reactions are taking place very quickly and some spontaneous reactions are taking place very slowly.

They will take space very slowly...
