Sodium Hydrogen Carbonate – LR Grade, 3kg

Sodium Hydrogen Carbonate, also widely known as Sodium Bicarbonate or Bicarbonate of Soda, is supplied in a large 3kg pack and manufactured to Laboratory Reagent (LR) grade. This high‑purity, versatile compound is a staple reagent in school science laboratories, suitable for safe and reliable use across a wide range of experiments and demonstrations.

Identified by CAS Number: 144‑55‑8 and with no UN number, sodium hydrogen carbonate is not classified as hazardous for transport when handled correctly. It is a white, crystalline powder that dissolves readily in water and decomposes on heating, producing carbon dioxide gas — a property that makes it particularly valuable in practical science teaching.

Supplied in a bulk pack ideal for regular classroom use, this reagent is easy to measure, store, and prepare, supporting consistent experimental results across multiple classes and year groups.
