Gases : GasRxnVolumes (10 Variations)
A gas phase reaction takes place in a syringe at a constant temperature and pressure. If the initial volume before reaction is 30 mL and the final volume after the reaction is complete is 15 mL, which of the following reactions took place? (Note: You can assume that you start with stoichiometric amounts of the reactants, the reaction goes to completion and that the gases behave ideally.)

Quantitative Analysis of Nail Polish Remover Using Nuclear Magnetic Resonance Spectroscopy Revisited  Markus M. Hoffmann, Joshua T. Caccamis, Mark P. Heitz, and Kenneth D. Schlecht
Substantial modifications intended for a second- or third-year laboratory course in analytical chemistry are presented for a previously described procedure using NMR spectroscopy to quantitatively determine analytes in commercial nail polish remover. The revised experiment introduces student collaboration to critically interpret a relatively large set of data.

An Inexpensive Semiautomatic Pressurized Microfiltration Device  E. Rodríguez-Fernandez, M. A. Vicente, J. J. Criado, and J. L. Manzano
Using the device shown, the filtration of small volumes (= 10 mL) of liquid can be facilitated by replacing the vacuum or manual pressure on the piston with pressure exerted by a rubber band on the piston. The filtration is thus conducted in a semiautomatic way.

Modification to Synthesis of Methyl Diantilis  William H. Miles
After we published the Synthesis of Methyl Diantilis, a Commercially Important Fragrance,we encountered a problem with the catalyst, Amberlyst-15, used in the second step. A revised laboratory procedure has replaced the original supplement available at JCE Online.

Conductivity Meter (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Conductivity Meter: this is a resource in the collection "ChemPages Laboratory Resources". A conductivity meter is used to measure the conductivities of electrolytic solutions. Electrodes on the device are dipped into a solution, and the solution's electrical conductivity is registered on the display. Electrical conductivity is defined as the transfer of an electric current through a solid or liquid. In electrolytic solutions, the current is carried by ions, as in solutions of salts, acids or bases. Conductivity is inversely proportional to the resistivity of the solution. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory. They have been put together for use as both a pre-laboratory preparation tool and an in-laboratory reference source.

Eppendorf Pipet (ChemPages Lab)  John W. Moore, Jerrold J. Jacobsen, Joe L. March
Eppendorf Pipet or Digital Pipettor: this is a resource in the collection "ChemPages Laboratory Resources". Digital pipettors deliver liquids in volumes from 1 mL to 1µL or less. They are sometimes called "micropipets", "Eppendorf pipets" or simply "Eppendorfs" after one of the more prevalent brands. The ChemPages Laboratory Resources are a set of web pages that include text, images, video, and self check questions. The topics included are those that are commonly encountered in the first-year chemistry laboratory.
