Product Code : SCL-CLE-14729
Indian Lab Suppliers supplies the Electrolysis of Water (Product ID: 14729) as part of its chemistry lab equipment range. It is a Hofmann-type apparatus that splits water into hydrogen and oxygen with a low-voltage direct current and collects each gas in its own graduated tube.
Quick Answer
Two vertical graduated gas tubes (10–50 mL depending on model) sit over inert electrodes, and a 3–12 V DC supply drives the reaction. Hydrogen collects at the negative electrode and oxygen at the positive one, in a volume ratio close to 2:1. Pure water conducts poorly, so a little dilute sulfuric acid or sodium sulfate is added as the electrolyte. Electrode material (graphite, platinum-plated or stainless steel) and body (borosilicate glass or acrylic) vary by model, so please confirm them at quotation; connecting wires, a stand and a manual are included.

Where This Is Used
It is used for teaching electrolysis, redox and decomposition reactions in school and college chemistry. Hydrogen is flammable: test it with a small lighted splint only, keep other flames away, wear eye protection and gloves with acid electrolytes, and use only a low-voltage DC supply.

Frequently Asked Questions
What voltage does it need?
3–12 V DC.
What volume ratio of gases forms?
About 2 volumes of hydrogen to 1 of oxygen.
Why add acid or salt to the water?
Pure water conducts poorly; a little electrolyte lets current flow.
