Question

Which of the following option is correct?

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

Answer 1

The correct option is A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1

Aluminium spontaneously reacts with moisture and oxygen and forms a thin but effective oxide layer of $A{l}_2{O}_3$ that prevents further oxidation.
$4Al\left(s\right)+3O_2\left(g\right)\to 2A{l}_2{O}_3\left(s\right)$
