A 22.1 mL sample of 0.334 M methylamine, CH3NH2, is titrated with 0.276 M hydrochloric acid. At the titration midpoint, the pH is Use the Tables link in the References for any equilibrium constants that are required.

200 mL of 0.1 M HCl is added to 400 mL of 0.1 M sodium acetate and water is added to give a final volume of 1 l (liter). What is the pH of the final solution?

An analytical chemist is titrating 109.3 ml. of a 0.8700 M solution of butanoic acid (HC,H,CO,) with a 0.9500 M solution of NaOH. The pK, of butanoic add is 4.82. Calculate the pH of the and solution after the chemist has added 36.93 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 = 0 X
