Ward's® AP Chemistry Investigation 13: Equilibrium: Can we Make the Colors of the Rainbow?

Avg. Ratings: 5.0 (1 Review)

Meets AP Science Practices 4, 5, and 6

  • Addresses Big Idea 6
  • Materials provided for 30 students working in pairs
  • Investigation includes updated literature aligned with new AP Chemistry curriculum standards
In this lab, chemical equilibrium and Le Chatelier's principle will be explored as students study the effect of concentration, pressure, volume, and temperature on systems at equilibrium. Students will be studying an acid-base-indicator equilibrium, a hydrated cobalt complex-alcohol equilibrium, and a seltzer water-indicator equilibrium. Students will be required to apply different stresses to these equilibrium reactions and observe how the system responds via a color change. The information learned from these tests will ultimately be used to produce solutions that make up all the colors of the rainbow. Includes bromothymol blue, hydrochloric acid, sodium hydroxide, sodium chloride, cobalt (II) chloride, ethanol, acetone, silver nitrate, seltzer water, methyl red, leur lock syringes and caps. Requires test tubes, available separately.

Awesome LeChatlier Lab! - Ward's has taken a lab with a lot of prep and made it one with easy set-up. Everything in the protocols from background to procedures to inquiry to assessments is very useful. My students love it as do my participants at APSI's. It will be one of your favorites.
