WebJan 18, 2024 · Summary. In this activity, students will use a simulation to create a variety of non-standard condition galvanic/voltaic cells. This simulation allows students to choose the metal and solution for each half cell, as well as the concentration of those solutions. Students will build concentration cells and other non-standard cells and record the ... WebGalvanic experiments since the contractions were often weak while the test of the ability of a metal to conduct the Galvanic fluid was whether or not the muscle contracted. Alexander von Humboldt had long been sensitive to the difference in natural excitability among frogs and the effect on the outcome of Galvanic experiments.
