1.	What is the difference between the forms .hydrolysis. and .hydration..
Answer» Solution :(iii) Hydrolysis Reaction : Due to high dielectric constant, it has a very strong hydrating tendency. It dissolves many ionic compounds. However, certain covalent and some ionic compounds are hydrolysed in water. `P_4O_(10(s)) + 6H_2O_((l)) to 4H_3PO_(4(aq))` `SiCl_(4(l)) + 2H_2O_((l)) to SiO_(2(s)) +4HCl_((aq))` `N_((s))^(3-) +3H_2O_((l)) to NH_(3(g)) + 3OH_((aq))^(-)` (IV) Hydrates Formation: From aqueous solutions many salts can be crystallised as hydrated salts. Such an association of water is of different types viz., (i)Coordinated water e.g., `[CR(H_2O)_6]^(3+) 3Cl^(-)` (II)interstitial water e.g., `BaCl_2. 2H_2O` (iii) hydrogen-bonded water e.g., `[Cu(H_2O)_4]^(2+) SO_4^(2-) . H_2O` in `CuSO_4 . 5H_2O`
