Potassium Carbonate (Pure) – LR Grade, 500g

Potassium Carbonate is a high quality Laboratory Reagent (LR) grade inorganic compound supplied in a 500g container, suitable for use in educational science laboratories. Commonly known as potash, this compound is widely used in school chemistry due to its clear alkaline properties and solubility in water.

The product has a CAS Number of 584‑08‑7 and no UN number assigned (UN: NR). Potassium carbonate is typically supplied as a white, crystalline powder that dissolves readily in water to form an alkaline solution. Clearly labelled and packaged, it supports safe handling and consistent experimental results when used in line with standard laboratory procedures.

This reagent is ideal for routine laboratory demonstrations and practical activities across a range of secondary science courses.
