Innovating Science® - Distance Learning: Acids, Bases and the pH Scale

In this lab, students will gain an understanding of the basic differences between the properties of acids and bases, learn the role of hydrogen and hydroxide ions in acidic and basic substances, and comprehend the nature of the pH scale with regards to acid and base strength. Students will examine the effects of acids and bases on several pH indicators, determine the pH of several common household materials, and use the knowledge gained to determine the identity of four unknown solutions. Instruction Manual and enough materials for 2 groups are included.
