An analytical chemist is titrating 227.3mL of a 1.200M solution of propionic acid HC2H5CO2 with a 0.5600M solution of NaOH . The pKa of propionic acid is 4.89 . Calculate the pH of the acid solution after the chemist has added 532.8mL 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.

As an Analytical chemist, you are designing a titration experiment to determine formic acid in food samples (formic acid is used as a preservative and antibacterial agent). You test your protocol by performing a titration of 100.0 mL of 0.050 M formic acid (FW = 46.03 g/mol) with a 0.10 M sodium hydroxide standard solution. For formic acid Ka = 1.80 x 10−4 You can ignore activity coefficients! (60 points total) Vb = Volume of base added NOTE: Just providing...
