Question 1
Calculate the pH of a 0.1 M solution of acetic acid (Ka = 1.8 × 10⁻⁵) using a quadratic equation.
💡 Hint: Remember to consider the approximation if x is small.
Question 2
A solution contains 0.1 M of a diprotic acid (H₂A), with Ka values being 1.0 × 10⁻⁴ for the first dissociation and 1.0 × 10⁻⁸ for the second. Find the pH.
💡 Hint: Take the first dissociation primarily at moderate concentrations.
