Answer 1

* Li OH es) - Litcago + oH caq soloilsion It gives bydroxy Lions. COH) ions. This reaction indicates that it is basic in nature. CiThus LiOH is Basic in nature. TOR 1912) * HF + H2O(1) - H₂ Ot caq) + f caq? al' It gives +30+ ions hence it is acidic, but the equilibrium ammw indicolēs that dissociation is incomplete. Hence HE is a weak acid. * HE cag Htcags + f cog) - TA It gives #t ions hence it is acidic, but the equilibrium arrow indicates that dissociation is incomplete. Hence HE is a weak acid. * HCl caq? + H₂O cago al cag + H₂O + cag) It gives HD ions hence it is acidic, The forward arrow indicales that hat undergoes complele dissociation giving H30+ ions. Hence it is a strong Aeid. | Ans: HCl caq) + H2O caq) Cicags & t30tcago Which of the following ionic compounds is INSOLUBLE in waler. 030.6 : JEG Liz P04 Insoluble in water. Since the size of the cation is smaller it is insoluble. All the other ionic compounds are soluble in water. .
