Description

Experiment Topics:

Measurement at galvanic voltage sources
Daniell cell, series and parallel circuits
Electrochemical potentials (voltage sequence)
Determination of the standard potentials of different metals and non metals
How potentials depend on concentration
How potentials depend on temperature
Charge and discharge of a steel accumulator
Leclanché cell
Measurement of pH values

A complete equipment set in a case for basic experiments on electrochemistry.
A cell block made of tough plastic, which can be unscrewed into two halves for ease of cleaning, allows four galvanic cells to be connected in parallel. A piece of filter paper stretched between the two halves of the cell acts as a diaphragm.
Includes a handy, high-resistance meter for measuring potential differences with very little current and measuring pH values with the help of the supplied pH measuring probe.
