Solution :-

A high value of dipole moment and dielectric constants (78.39 C2 /Nm2 ) makes water a universal solvent. Water is able to dissolve most covalent and ionic compounds. Owing to the ion-dipole interaction, Ionic compounds dissolve in water, whereas covalent compounds form hydrogen bonding and dissolve in water. Water can hydrolyze

→ metallic and non-metallic oxides

→ nitrides

→  phosphides

→ carbides

→ hydrides

and various other salts. During hydrolysis, H+ and \( OH^{–}\)  ions of water interact with the reacting molecule.

Certain reactions are:

\( CaC_{2}+H_{2}O\rightarrow C_{2}H_{2}+Ca(OH)_{2}CaO+H_{2}O\)

\( \rightarrow Ca(OH)_{2}NaH+H_2​O\)

\( \rightarrow NaOH+H_{2} \)
