Calculating the pH of a weak acid titrated with a strong base An analytical chemist is titrating 156.4 ml. of a 0.5500 M solution of formic acid (H,CO,) with a 1.000 M solution of NaOH. The p K, of formic acid is 3.74. Calculate the pH of the acid solution after the chemist has added 92.99 mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution...

During a titration of a weak base with a strong acid, you are slowing converting molecules of the weak base into molecules of its conjugate acid. For the hypothetical weak base, B we see the following: B (aq) + H30+ (aq) - BH+ (aq) + H20 (1) In the problem below you will be adding some strong acid, but not enough to reach the endpoint of the titration. 2.00 mL of hydrochloric acid added to the weak base 2.00M hydrochloric...
