State Core Objectives:

STANDARD VI:  Students will understand the properties that describe solutions in terms of concentration, solutes, solvents, and the behavior of acids and bases.

Objective 3:  Differentiate between acids and bases in terms of hydrogen ion concentration.

a.       Relate hydrogen ion concentration to pH values and to the terms acidic, basic or neutral.

b.       Using an indicator, measure the pH of common household solutions and standard laboratory solutions, and identify them as acids or bases.

c.       Determine the concentration of an acid or a base using a simple acid-base titration.

d.       Research and report on the uses of acids and bases in industry, agriculture, medicine, mining, manufacturing, or construction.

e.       Evaluate mechanisms by which pollutants modify the pH of various environments (e.g., aquatic, atmospheric, soil).
