Solutions of ammonium cyanide NH4CN, sodium cyanide NaCN, potassium cyanide KCN, calcium cyanide Ca(CN)2 and barium cyanide Ba(CN)2 are alkaline (due to the hydrolysis of cyanides) and attack aluminium. A general method for estimating $\mathrm{p}K_\mathrm{b}$ values is to use the equation $\mathrm{p}K_\mathrm{b} + \mathrm{p}K_\mathrm{a} = 14$ where $\mathrm{p}K_\mathrm{b}$ is that of the conjugate acid; in this case, applying it gives us $\mathrm{p}K_\mathrm{b}(\ce{CN-}) \approx 4.79$. In water, it is completely ionized, forming . Barium cyanide is a chemical compound with the formula Ba (CN) 2. It is synthesized by the reaction of hydrogen cyanide and barium hydroxide in water or petroleum ether. This white crystalline salt reacts with water and carbon dioxide in air slowly, producing highly toxic hydrogen cyanide gas. ^ Greenwood, Norman N.; Earnshaw, Alan (1997). If so, one way to find out is to combine the two equilibrium equations and their $K$ s. I don't want to give problem away completely, but think of it this way: The scale ranges from 0 to 14.
