Unit 10 - Acid Base Reactions

Acid Base Reactions Objectives

8.4 Acid-Base Reactions and Buffers - SAP-9.D - Explain the relationship among the concentrations of major species in a mixture of weak and strong acids & bases.

8.5 Acid-Base Titrations - SAP-9.E - Explain results from the titration of a mono- or polyprotic acid or base solution, in relation to the properties of the solution and its components.

8.7 pH and pKa - SAP-10.A - Explain the relationship between the predominant form of a weak acid or base in solution at a given pH and the pKa of the conjugate acid or the pKb of the conjugate base.

8.8 Properties of Buffers - SAP-10.B - Explain the relationship between the ability of a buffer to stabilize pH and the reactions that occur when an acid or a base is added to a buffered solution.

8.9 Henderson-Hasselbach - SAP-10.C - Identify the pH of a buffer solution based on the identity and concentrations of the conjugate acid-base pair used to create the buffer.

8.10 Buffer Capacity - SAP-10.D - Explain the relationship between the buffer capacity of a solution and the relative concentrations of the conjugate acid and conjugate base components of the solution.

Acid Base Reactions Big Ideas

Big Idea 2: Structure and Properties (SAP)

• Enduring Understanding SAP-9: The chemistry of acids and bases involves reversible proton-transfer reactions, with equilibrium concentrations being related to the strength of the acids and bases involved.

• Enduring Understanding SAP-10: A buffered solution resists changes to its pH when small amounts of acid or base are added.
