National Standards for Grade Levels 5-8
Introduce students to the colorful world of acid base indicators. Teach students how to choose an appropriate indicator and how specific indicators are commonly used. Includes Phenolphthalein for indicating basic solutions and use in standard acid-base titration, Universal Indicator for using over a wide range of acid-base pH, and Methyl Orange for testing strongly acid solutions. The kit includes one 30 ml dropper bottle of each Phenolphthalein, Universal Indicator, and Methyl Orange, a reproducible lab sheet for recording results when testing common substances, and six Universal Indicator Color Charts. The kit may be used in a wide variety of investigative applications. Utilizing an experimental approach, students can predict, observe, and analyze the pH of common household solutions, physiological fluids, environmental samples, and foods to become familiar with acid base chemistry and characterize the pH profiles of different classes of substances.
