What is the difference between the terms ‘hydrolysis’ and ‘hydration’ ?

Explanation

Hydrolysis:Interaction of `H^(o+)` and `.^(Θ)OH` ions of `H_(2)O` with the anion and cation of a salt respectively to give the original acid and original base is known as hydrolysis, e.g.
`underset("salt")(Na_(2)CO_(3))+H_(2)Oto underset("base")(2 NaOH)+underset("Acid")(H_(2)CO_(3))`

Hydration: Addition of water to ions or molecules to form hydrated ions or hydrated salts is known as hydration
`NaCl_(s)+(x+y)H_(2)Oto [(NaCH_(2)O)_(x)]^(o+)+[Cl(H_(2)O)_(y)]^(Θ)`
`CuSO_(4)(s)+5H_(2)O_(l)to CuSO_(4).5H_(2)O_(s)`
