Determining Gram-Equivalent Mass by Evolution of Hydrogen: An Improved Experiment.
Hopper, Marlon E.
Journal of College Science Teaching, v22 n6 p358-60 May 1993
Describes an experiment where the gram-equivalent mass of an unknown metal is determined by reacting the metal with dilute hydrochloric acid and collecting the evolved gas over water. This simple, reliable experiment routinely gives results within 1% of the accepted value. (PR)
