Unit 9 - Acid Base Solutions

Acid Base Solutions Objectives

8.1 Introduction to Acids and Bases - SAP-9.A - Calculate the values of pH and pOH based on Kw and the concentration of all species present in a neutral solution of water.

8.2 pH and pOH of Strong Acids and Bases - SAP-9.B - Calculate pH and pOH based on concentrations of all species in a solution of a strong acid or a strong base.

8.3 Weak Acid and Base Equilibria - SAP-9.C - Explain the relationship among pH, pOH, and concentrations of all species in a solution of a monoprotic weak acid or weak base.

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.

8.6 Molecular Structure of Acids and Bases - SAP-9.F- Explain the relationship between the strength of an acid or base and the structure of the molecule or ion.

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.

Acid Base Solutions 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.
