Challenge Problems
Push your limits with advanced challenges
Calculate the Kb for a weak base if you find 3% of it dissociates in a 0.2 M solution.
💡 Hint: Start by determining the [OH-] from the percentage dissociated.
If a base has Kb = 9.0 × 10⁻⁶, what is Ka for its conjugate acid?
💡 Hint: Use the Kw value at 25 °C to find Ka.
