North Carolina Essential Standards and Clarifying Objectives:

Chm. 3.2 Understand solutions and the solution process.

            3.2.1 Classify substances using the hydronium and hydroxide concentrations.

         Distinguish between acids and bases based on formula and chemical properties.

         Differentiate between concentration (molarity) and strength (degree of dissociation). No calculation involved.

         Use pH scale to identify acids and bases.

         Interpret pH scale in terms of the exponential nature of pH values in terms of concentrations.

         Relate the color of indicator to pH using pH ranges provided in a table.

         Compute pH, pOH, [H+], and [OH-].

            3.2.2 Summarize the properties of acids and bases.

         Distinguish properties of acids and bases related to taste, touch, reaction with metals, electrical conductivity, and identification with indicators such as litmus paper and phenolphthalein.

         Evaluate equilibrium constants as a measure of the extent that the reaction proceeds to completion.

            3.2.3 Infer the quantitative nature of a solution (molarity, dilution, and titration with a 1:1 molar ratio).

         Perform 1:1 titration calculations: MAVA = MBVB

         Determine the concentration of an acid or base using titration. Interpret titration curve for strong acid/strong base.
