Question

what happen when NaOH reactswithalumminium metal​

Answer 1

Answer:

Al is amphoteric in nature, so it can react with both acid and base. On treatment with NaOH, Al gives sodium aluminate salt and hydrogen gas. The reaction is highly exothermic.

$NaOH + Al$ ⇒ $Na_{2}AlO_{2$ $+ H_{2}$

Answer 2
