Abstract
In the first article, the fundamentals, applications, and instrumentation of the quartz-crystal microbalance (QCM) technique were described. The present article describes a typical student experiment with the QCM used as a mass sensor during the electrochemical deposition and dissolution of copper.

I. Fundamentals and Instrumentation
II. Measuring Viscosity

Supplement
The principles of operation of the QCM, description of equipment with remarks for instructors and examples of quizzes may be found in the Supplemental Material of our first article. Instructions for students related to the experiments described in this article are available here.

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
