Problem 1
Strong acids have a higher percent ionization than do weak acids. Why don't we use percent ionization as a measure of acid strength, rather than \(K_{a}\) ?
Problem 3
Using Le Châtelier's principle, explain why the concentration of \(\left[O H^{-}\right]\) is much lower in acidic solution than it is in neutral solution.
Problem 9
Predict and explain the relative acid strengths of \(H_{2} S\) and \(H C l\). Predict and explain the relative acid strengths of \(\mathrm{H}_{3} \mathrm{PO}_{4}\) and \(\mathrm{H}_{3} \mathrm{AsO}_{4}\).
