Consider the following statements :
The polar nature of water makes it

I. a very good solvent for ionic compounds
II. to act as an amphoteric substance
III. to form hydrates of different types

Which of the statements given above are correct?

The polar nature of water, arising from the electronegativity difference between oxygen and hydrogen, explains these properties:

• Statement I: Water's high dielectric constant and dipole moment allow it to solvate ions effectively through ion-dipole interactions, making it an excellent solvent for ionic compounds.
• Statement II: Water is amphoteric, meaning it can act as both an acid (proton donor) and a base (proton acceptor). This is facilitated by the polar O-H bond and the lone pairs on the oxygen atom.
• Statement III: Its polarity allows water to form various hydrates via coordinate covalent bonds with metal ions (coordinated water), hydrogen bonding with oxyanions, or by occupying interstitial sites in crystal lattices.

Therefore, all three statements are correct.
