Evaluation of Lemonade as a Buffer
Students use a powdered commercial lemonade formulation as a model for buffers and test its capacity to resist pH changes.
Introduction to Buffers
Students use titration and pH to investigate the components of a buffer and how it acts to resist pH change.
Investigation of Acid-Base Titrations
Students compare the pH titration profiles of strong, weak and polyprotic acids.
Applications of Le Chatelier's Principle
Students study equilibrium and the reversibility of chemical reactions using colorimetry and energy changes.
Building a Better Hand Warmer
Students use a temperature sensor to determine the heat of solution of a number of ionic compounds and propose a practical hand warmer design.
Kinetics of Crystal Violet Fading (Spectrometer)
Students determine the reaction order of crystal violet fading in the presence of sodium hydroxide.
Kinetics of Crystal Violet Fading (Colorimeter)
Students determine the reaction order of crystal violet fading in the presence of sodium hydroxide.
What Does Acid Rain Do To Coral Reefs?
Students use a pressure sensor to study what factors affect the reaction of calcium carbonate with acid.
Investigating Physical and Chemical Changes of Matter
Students use a variety of sensors and particle modeling to characterize physical and chemical changes of matter.
Percentage of H₂O₂ in Your Drugstore Hydrogen Peroxide
