Hofmann Voltameter Manufacturer,Supplier and Exporter in India

Hofmann Voltameter

Product Code : ILS-EAE-10803

Indian Lab Suppliers supplies the Hofmann Voltameter (Product ID: 10803) as part of its electrical and electronics range. It electrolyses water to show that it gives two volumes of hydrogen for every one volume of oxygen.

Quick Answer

The glass unit has two connected limbs, each graduated 50 × 0.2 ml, with stopcocks, joined by a tube to a funnel-shaped reservoir bulb. Removable carbon electrodes sit at the bottom of the limbs. Pure water conducts poorly, so a little electrolyte such as dilute sulphuric acid is added before a DC supply is connected. The gas volumes are read directly off the graduated limbs.

Where This Is Used

It is used in physics and chemistry classes for electrolysis and Faraday’s laws. Handle the glass with care, keep flames away from the hydrogen, and power it from a low-voltage DC source such as the Battery Eliminator (Product ID: 14571).
