WebTriprotic Acids. Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well. To illustrate this, let's calculate the H 3 O + , H 3 PO 4, H 2 PO 4-, HPO 42- , … WebAssume you have two solutions, one with the same number of sulfuric acid molecules and the other with citric acid molecules. Because sulfuric acid loses more protons to form more hydronium (H 3 O +) ions, the solution will be more acidic. The lower the pKa, similar to pH, the stronger the acid. Web3 O +] ≈ [Ka2(HS-) / S^2-)]. Refer to Figure 14.23 to sketch the following titration curves. Label the equivalence point. 1) Strong acid to which strong base is being added 2) Weak acid to which strong base is being added Lecture C2 Reading Assignment – Acid and Base Titration section 14.5 and 14.7 in OpenStax Polyprotic Acids (section 14.5) Titration … csts alberta
