  • What is the pH of 0.068M aqueous solution of sodium cyanide

    Feb 29, 2012· Kb = [HA} [OH-] / [A-] where [A-] represents the concentration of CN-(.068M). Kb = Kw / Ka = 1 x10-14 / 4.9 x 10-10 = 2 x 10-5. Since this is a salt solution which could be considered to have formed from the neutralization of a strong base (NaOH) and a weak acid (HCN), the Na+ will have no effect on the pH of the solution while the CN- ion will undergo hydrolysis:
