Question

Aluminium is more reactive than iron because its standard reduction potential is higher, still aluminium is less easily corroded than iron because: (A) it has higher reducing power and forms self-protective layer of Al2O3 (B) it has higher reducing power and does not react with oxygen so easily (C) A1 reacts with atmospheric carbon dioxide to form a self-protective layer of Al2O3 + Al4C3 (D) all of the above

Q. Aluminium is more reactive than iron because its standard reduction potential is higher, still aluminium is less easily corroded than iron because:

it has higher reducing power and forms self-protective layer of $A l_{2} O_{3}$

it has higher reducing power and does not react with oxygen so easily

A1 reacts with atmospheric carbon dioxide to form a self-protective layer of $A l_{2} O_{3} + A l_{4} C_{3}$

all of the above

$2 A l + \frac{3}{2} O_{2} \to Protective layer A l_{2} O_{3}$

Q. Aluminium is more reactive than iron because its standard reduction potential is higher, still aluminium is less easily corroded than iron because:

it has higher reducing power and forms self-protective layer of Al2​O3​

it has higher reducing power and does not react with oxygen so easily

A1 reacts with atmospheric carbon dioxide to form a self-protective layer of Al2​O3​+Al4​C3​

all of the above

2Al+23​O2​→Protective layerAl2​O3​​

it has higher reducing power and forms self-protective layer of $A l_{2} O_{3}$

A1 reacts with atmospheric carbon dioxide to form a self-protective layer of $A l_{2} O_{3} + A l_{4} C_{3}$

$2 A l + \frac{3}{2} O_{2} \to Protective layer A l_{2} O_{3}$
