Webis barium cyanide acidic or basic; is barium cyanide acidic or basic. It is also called as Proton theory of acid base. Acid. Ionic equilibri. An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid). Shouldn't the product formed depend on the alkyl group, say for a tertiary alkyl group, the reaction can go via $\mathrm{S_N1}$ mechanism for polar protic solvents and via $\mathrm{E2}$ for polar aprotic solvents and as the cyanide ion is strong base, the reaction is unlikely to go via $\mathrm{E1}$ and due to steric factors $\mathrm{S_N2}$ is also ruled out. In this way, is NaCN a strong or weak base? It, like most barium salts, is colorless, toxic, and water-soluble.
