Featured in PASCO’s College Chemistry Instructor Guide
College Instructor edition with 36 experiments covering introductory and general chemistry topics.
Use a colorimeter to determine the rate constant and the order of reaction.
Students determine the order of reaction by analyzing the reaction rate of crystal violet and NaOH.
Students gain experience conducting the following procedures:
Glass cuvette with cap
Beaker, 50-mL - 3
Syringe, 5-mL - 3
Watch glass, 4 in
0.1 M Sodium hydroxide (NaOH) - 20 mL
1.2 × 10–5 M Crystal violet - 20 mL
Water, distilled - 30 mL
This experiment may require software and an interface for data collection.
