Question 1
A solution contains 0.050 M of a weak acid with a Ka of 1.0 x 10^-5. Calculate the pH of the solution.
💡 Hint: Assume x is much smaller than 0.050 for simplifications.
Question 2
Given that pKa = 4.75, what is the relationship of Kb with respect to Kw at this pKa?
💡 Hint: Use the connected relationships of Ka, Kb, and Kw.
