The salt gives the most basic 0. 1 m solution in water is NaNo₂.
Basic solutions are those solutions in which the concentration of OH- ion will always be greater as compared to the concentration of H+ ion in the solution.
If the solution is basic so after the dissociation, the formation of a strong base and a weak acid is a must in the solution.
NaNo₂ gets dissociated in water in the form of NaOH and HNO₂ and NaOH is a strong base whereas HNO₂ is a weak acid due to which the solution becomes acidic.
Therefore, salt gives the most basic 0. 1 m solution in water NaNo₂.
