Potassium Meta Bisulphite Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-12336
Jlab Export is a leading Potassium Meta Bisulphite Manufacturer,and suppliers in India
Potassium Meta Bisulphite (code EL-CL-12336) is potassium metabisulphite, K2S2O5, a reducing salt that gives off sulphur dioxide when acidified. Teachers use it as a small-scale source of the gas and to show the reducing reactions of sulphites. Made in Ambala, India, it is one of the laboratory chemicals JLab manufactures.

Sulphur Dioxide and Reducing Reactions
With dilute hydrochloric or sulphuric acid the salt releases sulphur dioxide. The gas, or a solution of the salt, turns acidified potassium dichromate from orange to green and decolourises acidified potassium permanganate, the two usual tests for a sulphite. In water the metabisulphite ion reacts to form hydrogensulphite ions, which also reduce iodine to colourless iodide ions.
Related Sulphite and Oxidant Reagents
- Sodium Bisulphite — sodium hydrogensulphite, known for its aldehyde addition products.
- Potassium Permanganate — acidified, it is decolourised by sulphur dioxide and sulphites.
- Iodine Solution N/10 — iodine solution that hydrogensulphite ions reduce to iodide.
