I was reading a module on waste management. There were two interesting points.
High pH results in higher solubility of $\ce{CN-}$. I understand that for HCN: $$\ce{HCN ->H+ + CN-}$$
Higher pH means that equilibrium will be shifted rightwards and concentration of $\ce{CN-}$ will increase. But will cyanide salts like KCN, NaCN have the same high solubility at higher pH? If so, how?
Low pH results in greater solubility of toxic gases. How?
