Students will learn about acids and bases through a class discussion and then test a dilute acid and dilute base with neutral litmus paper to learn how the paper indicates something is acidic or basic. Once that skill is learned they can move on to test some common items that would be found around their house to determine if they are acids or bases. Optional: Extra litmus paper is included to test more items either from home or around the school building for a greater understanding of acids and bases. The activity contains enough materials for 6 groups of students.

Description

Students will determine the rate law for the reaction of crystal violet and sodium hydroxide. Students will also prepare dilutions of stock crystal violet solutions to generate a Beer's law calibration curve. This lab will require students to integrate prior chemistry knowledge involving spectroscopy, Beer's law, solution dilution, calibration curves, and chemical kinetics. The activity contains enough materials for 15 groups of students as well as a Teacher's Guide and Student Study Guide Copymasters. Meets Big Idea 4, Investigation 11, Primary Learning Objective 4.2.

Kit Includes:
1500mL Crystal Violet, 1%
1500mL Sodium Hyroxide, 0.2M
1000mL Deionized Water
