Sodium aluminate is manufactured by the dissolution of aluminium hydroxide (Al(OH)3) in a caustic soda (NaOH) solution. Aluminium hydroxide (gibbsite) can be dissolved in 20–25% aqueous NaOH solution at a temperature near the boiling point. The use of more concentrated NaOH solutions leads to a semi-solid product.
How is the formula for sodium aluminate derived?
Sodium aluminate is formed between one sodium ion and one aluminate ion. Therefore, the formula for sodium aluminate is NaAlO2, which is a solid, white compound.
Is sodium aluminate an acid or a base?
Simply stated, sodium aluminate is an alkaline form of aluminum which has been dissolved in caustic. Aluminum, because of its amphoteric nature, can be easily dissolved either in an acid or alkaline medium.
