Polyprotic Acids

Polyprotic Acids. Interesting Features of a plots. First, notice that the pH where two species concentrations are the same is around the pKa for that equilibrium. In fact, for polyprotic acids with pKa 's that differ by over 3 to 4 units, the pH is equal to the pKa . .

Chapter 8: Acids & Bases

Chapter 8: Acids & Bases. Acids are all around us. Foods like lemons, limes, and oranges contain acidic compounds. When wine is oxidized, it becomes acetic acid. Our muscles produce lactic acid. Our stomach uses hydrochloric acid to break down food. Acids.

The Base Dissociation Constant, K b

The Base Dissociation Constant, K b. The Base Dissociation Constant. A weak base, represented by B, reacts with water to form an equilibrium solution of ions. B (aq) + H 2 O ( l ) HB + (aq) + OH - (aq) The equilibrium expression for this general reaction is given as follows:
