A chemical salt formed when aluminum oxide (alumina) reacts with a strong base or alkali, commonly used in industrial processes.
From alumin- (aluminum) plus the chemical suffix -ate (indicating a salt or compound), coined in 19th-century chemistry to name compounds formed through aluminization reactions.
Sodium aluminate is used to purify drinking water by removing impurities—it's a clever example of how industrial chemistry developed practical applications from pure chemical research.
