Description of key information

Additional information

When sodium aluminate is diluted by water, it will hydrolyse readily and precipitation of Al(OH)3and release of free sodium ion will occur. Hydrolysis of aluminium ions has two possible “directions” towards a neutral pH, i.e. base hydrolysis and acid hydrolysis. Both acid and base hydrolysis of aluminium results in rapid precipitation of aluminium hydroxide. Sodium aluminate decomposes to aluminium hydroxide when added to water and can therefore not be considered as water soluble.

Sodium aluminate is an inorganic substance. Direct photolysis will not be an important abiotic degradation process.
