Neutralisation Involving Sparingly Soluble Bases – HSC Chemistry
This is part of the HSC Chemistry course under the topic Solution Equilibrium (Module 5) and Using Brønsted-Lowry Theory (Module 6).
HSC Chemistry Syllabus
- derive equilibrium expressions for saturated solutions in terms of `K_{sp}` and calculate the solubility of an ionic substance from its `K_{sp}` value
- calculate pH, pOH, hydrogen ion concentration ([H+]) and hydroxide ion concentration ([OH–]) for a range of solutions (ACSCH102)
- calculate the pH of the resultant solution when solutions of acids and/or bases are diluted or mixed
pH Calculation After Mixing Acid and Sparingly Soluble Base
This video discusses a harder pH calculation problem involving an acid and a sparingly soluble base. As a result, this problem requires application of knowledge from Module 5: Equilibrium and Acid Reactions and Module 6: Acid-base Reactions.
Practice Problem
Excess solid calcium hydroxide is added to a beaker containing 500.0 mL of 1.00 mol L−1 hydrochloric acid at 25ºC and the mixture is allowed to come to equilibrium.
Calculate the pH of the final solution.
Solution discussed in video above
