Question
What is the difference between the terms ‘hydrolysis’ and ‘hydration’?
✓
Answer
Hydrolysis is a chemical reaction in which a substance reacts with water under neutral, acidic or alkaline conditions.
$\text{Na}_2\text{CO}_3\ +\ 2\text{H}_2\text{O}\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ \ \ }2\text{NaOH}\ +\ \text{H}_2\text{CO}_3\\ \text{ Salt 1} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Base 2}\ \ \ \ \ \ \ \ \text{ Acid 1}$
Hydration on the other hand is the property of a chemical compound to take up molecules of water of crystallisation and get, hydrated.
$\text{Cu}\text{SO}_4(\text{s})\ +\ 5\text{H}_2\text{O(l)}\xrightarrow{\ \ \ \ \ \ \ \ \ \ \ \ \ }\text{CuSO}_4\ 5\ \text{H}_2\text{O}(\text{s})\\ \text{colorless} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{(Blue)}$
