Question: Aspirin is a weak acid.
(a) Calculate pH of 0.2M solution of aspirin at 25 degrees celsius (Ka = 3.0 x 10^-4 at 25 degrees celcius).
(b) Determine the percent ionisation
(c) Explain qualitatively the effect of adding 0.01M hydrochloric acid to the aspirin solution.
(d) Calculate the pH of the resulting solution
(e) Determine the percent ionisation of the aspirin under these conditions
