MCQ
What happens when sodium hydroxide is reacted with aluminum metal?
- ANo reaction occurs
- ✓A complex salt and hydrogen gas are produced.
- CA simple precipitation reaction occurs.
- DSodium hydroxide is neutralized by aluminum.
✓
Answer
Correct option: B.
A complex salt and hydrogen gas are produced.
(b) A complex salt and hydrogen gas are produced.
Explanation :
When sodium hydroxide reacts with aluminum metal, aluminum demonstrates its amphoteric nature. The reaction forms sodium aluminate, a complex salt, and hydrogen gas is released. The reaction can be represented as : $2 Al +2 NaOH +6 H _2 O \rightarrow$ $2 NaAl ( OH )_4+3 H _2.$
