In this lab, you will gain an understanding of the basic differences between the properties of acids and bases, learn the role of hydrogen and hydroxide ions in acids and bases, 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 chemical pH indicators, determine the pH of several common household materials, and use the knowledge gained to determine the composition of four unknown clear solutions. Kit contains enough materials for 15 groups.
