Experiment set CHEMISTRY 4: ELECTROCHEMISTRY 1

Description

Specially developed equipment

Designed specifically for the lower secondary school level, this experiment set helps students learn the fundamentals of electrochemistry simply and rapidly. For most of the experiments, special equipment has been developed and perfectly matched. As a result, the experiments can be set up and dismantled quickly and succeed with a high level of safety, reliability and accuracy. Ion migration, for example, can be demonstrated very impressively even with voltages below 12 volts using the associated MEKRUPHY device.

The MEKRUPHY experimentation system leaves nothing to chance. Thanks to student-oriented dimensioning and sophisticated design down to the smallest detail, the water decomposition cell of the Hofmann apparatus can be used to make a very accurate and rapid quantitative determination of the volumetric relationships of the gases generated. The electrodes are mounted on the sides here in order to ensure that they do not fall out. A smooth actuating three-way cock system is provided for oxygen and hydrogen detection. Similarly, the Faraday Laws can be studied and derived both qualitatively and quantitatively with precision.
