Challenge Problems
Push your limits with challenges.
Question 1
A weak acid HA has a concentration of 0.1 M and has an equilibrium concentration of H⁺ at 0.006 M after dissociation. Calculate the Ka and the percent ionization.
💡 Hint: Define equilibrium concentration with respect to the initial concentration.
Question 2
A solution contains 0.050 M of a weak acid with a Ka of 3.20 × 10⁻⁴. Calculate the equilibrium concentrations of all species when it reaches equilibrium.
💡 Hint: Set up the equilibrium expression correctly to find the concentration.
