Answer:
Explanation:
Aluminium reacts with both acids as well as bases. It is an amphoteric metal.
When aluminium is treated with dilute sodium hydroxide it forms a salt called sodium tetrahydroxoaluminate and hydrogen gas.
2Al +2 NaOH + 6H2O → 2Na[AlOH4] +3H2
This sodium aluminate salt is used in water treatment plants for softening systems and to improve flocculation and also used in construction for accelerating the solidification of concrete.
