About This Product
With the porous pot standing inside the copper vessel and the zinc rod in its own compartment, students connect a high-impedance voltmeter to the two 4 mm sockets, identify the polarity and record the cell EMF. The set-up supports lessons on oxidation, reduction, electron transfer and ionic conduction through a porous separator, and lets an Electrical And Electronics class compare a chemical cell with electronic DC sources. Gloves and eye protection are needed when handling the copper and zinc salt solutions.
Frequently Asked Questions
Q1. Which electrode of the Daniell cell is positive?
The copper outer vessel is the positive electrode and the zinc-amalgam rod is the negative electrode.
Q2. What is the porous pot for?
It keeps the two electrode solutions apart while allowing the ionic movement needed to complete the internal circuit.
Q3. Can a standard laboratory voltmeter be connected?
Yes. Both electrodes have 4 mm terminal sockets for compatible laboratory leads; a high-impedance voltmeter is used to read the EMF.
