$23.09
SKU IS7046
  • Kit demonstrating electrolysis, redox reactions, and acid/base reactions
  • Universal indicator solution shows how electrolytic cells work by turning a solution different colors based on the pH
  • Great demonstration for chemistry classrooms and labs
  • Kit contains enough material to perform the demonstration 5 times
  • Includes SDSs for all materials, teacher's manual, and student study guide copymasters

Study oxidation-reduction, electrolysis and acid-base reactions as Universal Indicator is added to an aqueous sodium sulfate solution. When two carbon electrodes are connected to a battery and placed in the solution, a rainbow of colors forms as the water is electrolyzed. There are enough materials to complete the demonstration 5 times. Aligned to the Next Generation Science Standards (NGSS)* Disciplinary Core Ideas: PS1.A; PS1.B Performance Expectations: MS-PS1-2; HS-PS1-2 Cross Cutting Concepts: Patterns Engineering Practices: Analyzing and Interpreting Data; Scientific Knowledge is Based on Empirical Evidence; Constructing Explanations and Designing Solutions Kit Includes: 50 mL Sodium Sulfate Solution, 1M 6 mL Universal Indicator 1 Red Connecting Wire 1 Black Connecting Wire 12 Carbon Electrodes 2 Petri Dishes
