Unformatted text preview: What is the pH of the buffer solution prepared by adding 0.200 mol of solid NaOH to 1.000 L of 0.500 M HCN solution? (K a = 6.2 x 10-10 for HCN; assume no change in volume when the NaOH is added.) 5. Consider a titration in which NaOH is being added to a flask which originally contains 1.0 liter of 1.0 M HX. The titration curve for this process is shown below. pH Volume NaOH added Based on this data, what is the approximate K a for acid HX?...
