Acid-Base Equilibria

Acid-Base Equilibria. Solutions of a Weak Acid or Base. The simplest acid-base equilibria are those in which a single acid or base solute reacts with water. In this chapter, we will first look at solutions of weak acids and bases.

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.

Neutralization Reactions for Polyprotic and Polybasic Species

Neutralization Reactions for Polyprotic and Polybasic Species. Polyprotic Acids. The titration curves we have considered so far have a single defined equivalence point, because the acids are monoprotic . They have a single proton (H + ) that may dissociate.
