Question

Which is not correct?
(a) Al acts as a reducing agent
(b) Al does not react with steam even at higher
temperature
(c) Al forms a number of alloys with other metals
(d) Al is ionic in all its compounds

Answer 1

Answer:

B

Explanation:

Aluminium is a very reactive metal and reacts vigorously with water to form it's oxide

So it easily reacts with steam

Answer 2

The statement that is incorrect about Al is that Al does not react with steam even at higher temperatures (option b).

• Aluminium is an element with thirteen total electrons and a valency of +3 or three electrons in its outermost shell.

• During a redox reaction, Al serves as a powerful reducing agent, losing its elctrons to other elements.

• Other metals, such as nickel and copper, combine with Al to make alloys. Alnico, for example, is an aluminum alloy.

• Because of its highly electropositive character, Al is ionic in compounds. There is an exception, however, in the case of chlorides.

• Al, on the other hand, reacts with steam to produce oxides and release hydrogen as a gas. It acts as a barrier between the metal and the environment.

• Because Al has a great affinity for oxygen, this is the case.

• As a result, the notion that aluminum does not react with steam is incorrect.
