Question 1
A solution of a weak base B has a Kb = 1.0 x 10^-5. If the initial concentration of B is 0.1 M, calculate the concentration of OH- at equilibrium.
💡 Hint: Set up an ICE table and don't forget to determine the equilibrium concentrations correctly.
Question 2
A buffer solution contains 0.1 M ammonia and 0.1 M ammonium chloride. Calculate the pH of the solution given Kb for ammonia is 1.8 x 10^-5.
💡 Hint: Remember to convert Kb to pKb and apply the Henderson-Hasselbalch equation effectively.
