A student is asked to determine the value of Ka for hydrocyanic acid by titration with potassium hydroxide. The student begins titrating a 47.1 mL sample of a 0.574 M aqueous solution of hydrocyanic acid with a 0.285 M aqueous potassium hydroxide solution, but runs out of standardized base before reaching the equivalence point. The student's last observation is that when 34.7 milliliters of potassium hydroxide have been added, the pH is 9.134. What is Ka for hydrocyanic acid based...
