Sodium Aluminate vs. Sodium Meta Aluminate: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 22, 2024
Sodium aluminate is a chemical compound with the formula NaAlO2, whereas sodium meta aluminate is its anhydrous form with a different structure.

Key Differences

Sodium aluminate, represented by the chemical formula NaAlO2, is a compound where sodium and aluminum are bonded with oxygen. Sodium meta aluminate, on the other hand, is a related compound but with a distinct anhydrous structure, often denoted as NaAlO2 as well but differs in its crystalline form.
