Challenge Problems
Push your limits with challenges.
Question 1
Calculate Kb for a weak acid with Ka = 1.0 × 10⁻⁸. Explain the significance of this value in relation to its conjugate base.
💡 Hint: Remember Kw's value at 25°C.
Question 2
If the Kw shifts to 1.0 × 10⁻¹³ due to temperature changes, how would that affect Kb calculations for a given Ka?
💡 Hint: Think about how temperature can affect equilibrium situations.
