Calculate the pH of a solution that is prepared by dissolving 0.470 mol of hydrocyanic acid (HCN, Ką= 6.17x10-10) and 0.164 mol of acetylsalicylic acid (HC,H-O4, Ka= 3.40×104) in water and diluting to 3.00 L. Also, calculate the equilibrium concentrations of HCN, CN", HC,H-O4, and C,H-O4. Do not make an approximation unless the initial acid concentration is greater than 1000 x K. (Hint: The pH will be determined by the stronger acid of this pair.) pH = [HCN] =| M [CN]= M [HC3H¬O4] = M [C9H¬O4]=| M
