What is formed when sodium hydroxide (NaOH) reacts with aluminum in a solution?
- AAluminum oxide and hydrogen gas
- ✓Sodium aluminate and hydrogen gas
- CAluminum chloride and sodium gas
- DSodium chloride and water
✓
Answer
Correct option: B.
Sodium aluminate and hydrogen gas
(b) Sodium aluminate and hydrogen gas
Explanation : When sodium hydroxide reacts with aluminum, it forms sodium aluminate ( $NaAlO _2$ ) and hydrogen gas. This reaction is facilitated by the breakdown of the aluminum oxide layer in the presence of $NaOH.$
