What is the difference between the terms ‘hydrolysis’ and ‘hydration’?
Advertisements
उत्तर
Hydrolysis is defined as a chemical reaction in which hydrogen and hydroxide ions (H+and OH– ions) of water molecule react with a compound to form products. For example:
\[\ce{NaH + H_2O -> NaOH + H_2}\]
Hydration is defined as the addition of one or more water molecules to ions or molecules to form hydrated compounds. For example:
\[\ce{CuSO_4 + 5H_2O -> CuSO_4 . 5H_2O}\]
