Post Utme Ksu 2021 Chemistry Question 28
Practice objective / multiple choice question 28 from the 2021 Post Utme Ksu Chemistry examination.
A 1.0 M solution of NaOH is titrated with a 1.0 M solution of HCl. The initial pH of the NaOH solution is 12. Calculate the pH of the solution after the addition of 20 mL of HCl, given that the dissociation cons\tant of HCl is 10^\( -7 \) and the temperature dep\endence of the dissociation cons\tant is described by the equation \( \log_{10} K_a = -\frac{1000}{T} + 2.303 \log_{10} a \), where ( a ) is the activity of the solvent.
