A 1.00-gram sample of acetic acid (HOAc MW = 60.05 g/mole, Ka = 1.8 x 10-5) was contaminated with some sodium chloride (NaCl). The whole sample was dissolved in 25.00mL of water as well as this solution was titrated with 35.00mL of 0.1000 M NaOH to reach the endpoint.
a. Compute the purity of acetic acid present in the sample in weight%. Define what was the pH of the solution after addition of 15.00mL of 0.1000 M NaOH
Explain what was the pH of the solution at the equivalence point?
