Cyanide salts such as sodium cyanide are amoung the most rapidly acting of all known poisons and act by inhibiting respiration.

a) Determine the pH of a solution of 0.0054M sodium cyanide (assuming complete dissociation) and state whether sodium cyanide is an acidic, basic or neutral salt (Ka HCN = 4.9×10^-9)

b) If the current biological toxicity limit of cyanide for the average male is 8.9×10^-6M, is the solution described above toxic?
