  1. Use the relationship between the Ka and Kw expressions to find an unknown Kb value.
    1. Ethanoic acid, or acetic acid CH3COOH is a weak acid with Ka = 1.4*10-5.1
      1. Write the formula of its conjugate base.
      2. Find the Kb for its conjugate base using the relationship between Ka/Kb and Kw.
    2. Explain using the Ka/Kb expression why Ka and Kb values are not normally used when studying strong acids and bases.
