Detailed explanation-1: -Hydrolysis (/haɪˈdrɒlɪsɪs/; from Ancient Greek hydro-‘water’, and lysis ‘to unbind’) is any chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile.
Detailed explanation-2: -Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water, ” a reaction in which a water molecule is used during the breakdown. During these reactions, the polymer is broken into two components.
Detailed explanation-3: -Splitting water into its two components is much easier to do and is called water electrolysis. Making hydrogen or oxygen this way seems simple. But as you probably suspected, this reverse reaction needs an energy input, which is why it is also called an endothermic reaction.
Detailed explanation-4: -Hydrolysis involves the reaction of an organic chemical with water to form two or more new substances and usually means the cleavage of chemical bonds by the addition of water.
Detailed explanation-5: -As a redox reaction, water splitting consists of the reduction reaction 4H+ + 4e– → 2H2 and the oxidation reaction 2H2O → O2 + 4H+ + 4e–, which produce hydrogen and oxygen, respectively. They are correspondingly abbreviated as HER (hydrogen evolution reaction) and OER (oxygen evolution reaction).
