The total [H +] from the two acids is 0.51 M and [OH - ] from NaOH is 0.62 M. Therefore, 0.51 moles per liter of H + will react with 0.51 moles per liter of OH - to form water. That leaves a 0.11 M NaOH solution. The pOH of a 0.11 M NaOH solution is 0.96 pOH units, and the pH is 13.04 pH units.
First thing first, calculate the total volume of the resulting solution. #V_"total" = "100.0 mL + 50.0 mL + 100.0 mL"# #V_"total" = "250.0 mL"# Now, you are dealing with two strong acids that ionize completely in aqueous solution. Both nitric acid and hydrochloric acid produce hydronium cations in #1:1# mole ratios, so you know that
d. 3.3 × 10-10 M. In deciding which of two acids is the stronger, one must know: a. the concentration of each acid solution. b. the pH of each acid solution. c. the equilibrium constant of each acid. d. all of the above. e. both A and C must be known. c. the equilibrium constant of each acid.
