The pH of a cyanoacetic acid/sodium cyanoacetate buffer in which the concentration of the weak acid component is 0.140 M and the concentration of the conjugate base is 0.070 M is 2.16. Suppose 0.144 g of solid NaOH are added to 100 mL of this buffer solution. What is the pH after the addition? Click here for the table of lonization Constants of Weak Acids. Please enter your answer with 2 decimal places.

Express the solubility equilibrium of the generally insoluble salt CuOH.

A buffer solution contains 0.235 M ammonium bromide and 0.314 M ammonia. If 0.0164 moles of hydrobromic acid are added to 125 mL of this buffer, what is the pH of the resulting solution? (Assume that the volume change does not change upon adding hydrobromic acid) pH =

An analytical chemist is titrating 111.5 mL of a 0.2600M solution of acetic acid (HCH,CO,) with a 0.5100M solution of NaOH. The p K, of acetic acid is 4.70. Calculate the pH of the acid solution after the chemist has added 10.45 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places. pH = |

A buffer solution contains 0.240 M nitrous acid and 0.349 M potassium nitrite. If 0.0367 moles of perchloric acid are added to 225 mL of this buffer, what is the pH of the resulting solution ? (Assume that the volume change does not change upon adding perchloric acid) pH =

A solution of a weak acid is titrated with a standard solution of a strong base. The progress of the titration is followed with a pH meter. Which of the following observations best describes what would occur? Initially the pH of the solution increases slowly, and then it increases much more rapidly, before increasing slowly again At the equivalence point, the pH is 7 The pH of the solution gradually decreases throughout the experiment After the equivalence point, the pH becomes constant because this is the buffer

A buffer solution contains 0.221 M hydrocyanic acid and 0.453 M potassium cyanide. If 0.0495 moles of nitric acid are added to 225 mL of this buffer, what is the pH of the resulting solution? (Assume that the volume change does not change upon adding nitric acid) PH
