Aluminium Hydroxide – LR Grade, 500g

Aluminium Hydroxide is a white, inorganic compound supplied in a 500g pack and manufactured to Laboratory Reagent (LR) grade. It is widely used in educational science laboratories for teaching fundamental concepts in inorganic chemistry, including metal hydroxides, amphoteric behaviour, and precipitation reactions.

Identified by CAS Number: 21645‑51‑2 and carrying no UN number, aluminium hydroxide is not classified as hazardous for transport when handled correctly. It is insoluble in water and demonstrates characteristic reactions with both acids and alkalis, making it particularly useful for safe and clearly observable classroom experiments.

Supplied in a generous quantity suitable for repeated classroom use, Aluminium Hydroxide LR Grade is easy to store, measure, and incorporate into practical lessons across multiple year groups.
