Product Details

Are cis and trans isomers interchangeable, and do they have different properties? Discover the answers to these fundamental organic questions in this quick and easy Vial Organic™ lab. Maleic acid (cis) is converted into fumaric acid (trans) using heat and an acid catalyst. After isolating the fumaric acid, its pH, solubility and melting point are compared to maleic acid to demonstrate how two geometric isomers can be quite different. Great lab to introduce isomers, organic acids and the use of physical properties to identify organic compounds.
• Requires immersion heaters or hot plates.
• Includes reaction vials, Beral-type pipets, maleic acid, hydrochloric acid, cresol red, capillary tubes and instructions.

Complete for 24 students working in pairs.

Performance Expectations

HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-6: Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
