| Statement 1: Articles made of aluminium do not corrode even though it is an active metal. |
| Statement 2: Aluminium reacts with air to form a layer of oxide due to which it does not react further. |
A) Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B) Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C) Statement 1 is true and statement 2 is false.
D) Both statements 1 and 2 are false.
Correct Answer: A
Solution :
Aluminium spontaneously forms a thin but effective oxide layer of \[A{{l}_{2}}{{O}_{3}}\]that prevents further oxidation. \[4A{{l}_{(s)}}+3{{O}_{2(g)}}\xrightarrow{{}}2A{{l}_{2}}{{O}_{3}}_{(s)}\]
