3 cards from this section. Quick, good the night before a test.
Define Ka and Kb.
Reference their roles in measuring strength.
What is the relationship between Ka and Kb?
Think about how they relate to the ion product of water.
What does Ka represent?
Think of 'A' for Acid.
True or False: Kb is always larger than Ka for a conjugate acid-base pair.
Consider the relationship between strength and dissociation.
Calculate Kb for a weak acid with Ka = 1.0 × 10⁻⁸. Explain the significance of this value in relation to its conjugate base.
Remember Kw's value at 25°C.
If the Kw shifts to 1.0 × 10⁻¹³ due to temperature changes, how would that affect Kb calculations for a given Ka?
Think about how temperature can affect equilibrium situations.
