In the Thirteenth Edition, all experiments were carefully edited for accuracy and safety. Pre-labs and questions were revised and several experiments were added or changed. Two of the new experiments have been added to Chapter 11.
- NEW! Solubility and the Effect of Temperature on Solubility is a new experiment in which the students measure the solubility above and below ambient temperature to generate a solubility curve. The students also determine the mass of an unknown solid in a saturated solution and then read a graph to identify the unknown solid.
- NEW! Freezing Point Depression is an experiment that replaces Colligative Properties: Freezing Point Depression and Molar Mass. It now uses lauric acid, a non-toxic, non-flammable and and inexpensive compound, in place of cyclohexane as the solvent used to determine the molar mass of an unknown organic compound.
- NEW! Enthalpy of Vaporization and Clausius–Clapeyron Equation is a new experiment that students perform to determine the enthalpy of vaporization of a compound by measuring the vapor pressure as a function of temperature.
- NEW! Experiments concerning equilibrium thermodynamics and crystalline solids have been added.
- NEW! Text references to the corresponding sections of Chemistry: the Central Science have been added.
- NEW! "Give it Some Thought" (GIST) questions aid the student in understanding the principles exemplified by the experiment
- NEW! More helpful hints in the Annotated Instructor’s Edition (AIE) have been added.
