Electrochemistry lists 10 items for cells and electrolysis in school and college labs: two classic primary cells (Daniell and Leclanché), four simple cell plates, a set of electrodes in six metals, a carbon electrode, and two electrolysis apparatus. The dimensions below are those given in each listing.

Cells

Item	What the listing specifies
Daniel Cell	Heavy-gauge copper outer vessel 150 x 100 mm with a perforated shelf for copper sulphate crystals, a porous pot and an amalgamated zinc rod on a supporting cap; 4 mm socket terminals on the zinc rod and the copper vessel
Leclanche Cell	HDPE container 90 x 90 x 150 mm with a rim shaped to hold the zinc rod; porous pot with a carbon rod in powdered carbon and manganese dioxide depolariser; EMF of about 1.5 V
Simple Cell Plate, Copper, Zinc, Lead and Carbon	Each plate 125 x 50 mm with a 4 mm socket terminal, sold separately

The four simple cell plates let a class build a simple cell from any two different plates and compare the pairs. The Daniell and Leclanché cells come complete, and the Daniell cell’s copper vessel doubles as its copper electrode.

Electrodes and electrolysis

Item	What the listing specifies
Electrodes, Six Metals	Ten electrodes: one carbon rod, one nickel, and two each of copper, iron, zinc and aluminium; each 4 x 3/4 inch, the carbon rod 4 inches, with a large surface-to-mass ratio
Carbon Electrode	Carbon rod 100 mm long and 5 mm in diameter, for electrolysis cells and general use
Electrolysis Cell, pH Type	Open-ended glass tube with two carbon electrodes in a rubber stopper, and collecting tubes; crocodile-clip connections, with an insulating strip in the bung to stop the clips shorting
Hoffman Electrolysis Apparatus	Hoffman H-piece on a black acrylic panel with adjustable clamps; runs on a 9 V battery or DC supply; supplied with assembly instructions

The Hoffman apparatus is the one for collecting and comparing the volumes of gas from each electrode. Its dark panel gives contrast for reading the volumes, and the panel and clamps protect the glass H-piece in use and in storage. The pH-type cell is listed for quick demonstrations of electrolysis.

Questions buyers ask

What EMF does the Leclanché cell give?
About 1.5 volts, according to its listing.

What power supply does the Hoffman apparatus need?
A 9 V battery or a DC power supply.

Which metals are in the six-metal electrode set?
Carbon, nickel, copper, iron, zinc and aluminium: ten electrodes in all, with two each of copper, iron, zinc and aluminium.

Are the simple cell plates sold as a set?
They are listed separately, as copper, zinc, lead and carbon plates, each 125 x 50 mm with a 4 mm socket terminal. Order at least two different metals per cell.
