The conjugate base of a strong acid has very little impact on the pH of the solution (with the case of Cl- and its conjugate acid, HCl). Again, the cations (\(K^+\) and \(Na^+\)) have essentially no acidic character, but the anions (\(CN^\) and \(CH_3CO_2^\)) are weak bases that can react with water because they are the conjugate bases of the weak acids \(HCN\) and acetic acid, respectively and they have Ka > 1 x 10-14. If, however, the anion is the conjugate base of a weak acid, the solution will be basic. The decrease in electron density weakens the OH bonds in the water molecules and makes it easier for them to lose a proton. BASE (wikipedia) Join. This salt is acidic. LIST ACID. Become a Study.com member to unlock this answer! While phosphoric acid is quite acidic, it is evident that it is, indeed, a weak acid because of the lack of full dissociation in water; a 1 M solution of strong acid would be around 0 (0 for monoprotic species, possibly less for diprotic due to an additional hydrogen ion). b) it is acidic in nature. Favourite answer . C. acidic, because of the hydrolysis of CH3NH3+ ions. - Aqueous solution of Na2CO3 is alkaline because: a) it is basic in nature.
