Apparatus for the Electrolysis of Salts
Product Code : SCL-CL-11451
Apparatus for the Electrolysis of Salts (SKU SCL-CL-11451) is a glass U-tube cell with graphite electrodes in which a salt solution is split by direct current, so that the products formed at the anode and cathode can be seen and tested separately in each limb. It is used in school and college chemistry to teach electrolysis of aqueous solutions. Schools, colleges, institutes, distributors and tender contractors can obtain it from Science Lab Supplies, which supplies it from Ambala, India.
Specifications
The cell is a glass U-tube of 15 mm diameter. A rubber stopper holds the 60 mm graphite electrode in the solution, electrical conductor wire connects it to the external DC supply, and the two limbs of the U-tube keep the anode and cathode products apart.

Applications and Experiments for the Electrolysis of Salts Apparatus
The U-tube cell lets students see which products form at each electrode when a salt solution is electrolysed, for example chlorine and hydrogen from brine or iodine from potassium iodide. Because the limbs keep products apart, each can be identified with a simple test or indicator.
- NCERT Class 10 science: electrolysis of brine and the chlor-alkali process.
- Class 12 chemistry: products of electrolysis of aqueous salt solutions with inert electrodes.
- B.Sc. practicals: comparing the behaviour of different salt solutions in the same cell.
- Indicator demonstrations: colour changes at the anode and cathode limbs.
Electrolysing chloride solutions releases chlorine, a toxic gas. Keep currents and run times short, work in a ventilated room or fume cupboard, and let students handle the cell only under supervision.
Standard Scope of Supply
The apparatus comes with the 15 mm glass U-tube, graphite electrode (60 mm), rubber stopper and electrical conductor wire. A DC power supply, stand and the salt solutions are not part of the listing and can be quoted separately.
Packing, MOQ and Lead Time
Ask for one cell or a class set of cells and the quotation will list the packing, delivery time and price for exactly that number. As a chemistry lab instruments supplier, we can add stands, spare electrodes and glassware to the same quotation.

Frequently Asked Questions
Why are graphite electrodes used?
Graphite is an inert electrode material, so it takes little part in the reaction and the products seen come mainly from the salt solution and water.
Which salts can be electrolysed in this cell?
Common school choices are sodium chloride, potassium iodide and copper sulfate solutions. Choose salts and concentrations according to your syllabus and your laboratory's safety rules.
Who supplies the Apparatus for the Electrolysis of Salts?
Science Lab Supplies supplies this U-tube cell from Ambala, India, directly to schools and colleges and through quotations for distributors and tender contractors.
Is a power supply included?
No. The listing covers the U-tube, electrode, stopper and wire. Use the low-voltage DC supply already in your lab, or ask for one on the quotation.
