11.1 Titration & Titration Curves
LO 6.12 I can reason about the distinction between strong and weak acid solutions with similar values of pH, including the percent ionization of the acids, the concentrations needed to achieve the same Ph, and the amount of base needed to reach the equivalence point in a titration.
LO 6.13 I can interpret titration data for monoprotic or polyprotic acids involving titration of a weak or strong acid by a strong base (or a weak or strong base by a strong acid) to determine the concentration of the titrant and the pKa for a weak acid, or the pKb for a weak base.
LO 6.15 I can identify a given solution as containing a mixture of strong acids and/or bases and calculate or estimate the pH (and concentrations of all chemical species) in the resulting solution.
LO 6.16 I can identify a given solution as being the solution of a monoprotic weak acid or base (including salts in which one ion is a weak acid or base), calculate the pH and concentration of all species in the solution, and/or infer the relative strengths of the weak acids or bases from given equilibrium concentrations.
LO 6.19 I can relate the predominant form of a chemical species involving a labile proton (i.e., protonated/deprotonated form of a weak acid) to the pH of a solution and the pKa associated with the labile proton.

11.2 Buffers
LO 5.16 I can use Le
Chatelier's principle to make qualitative predictions for systems in
which coupled reactions that share a common intermediate drive formation
of a product.LO 6.18 I can design a buffer solution with a target pH and buffer capacity by selecting an appropriate conjugate acid-base pair and estimating the concentrations needed to achieve the desired capacity.
LO 6.20 I can identify a solution as being a buffer solution and explain the buffer mechanism in terms of the reactions that would occur on addition of acid or base.
Groundwork for
LO 6.23 I can interpret data regarding the relative solubility of salts in terms of factors (common ions, pH) that influence the solubility.
