Given below are two statements; one is labelled as Assertion A and the...
Assertion A: The amphoteric nature of water is explained by using Lewis acid/base concept.
Reason R: Water acts as an acid with NH3 and as a base with H2S.
The correct answer is option D: A is false, but R is true.
Explanation:
Amphoteric Nature of Water:
Water is considered as an amphoteric substance because it can act as both an acid and a base. It can donate a proton (H+) to behave as an acid and accept a proton to behave as a base. The amphoteric nature of water can be explained using the Lewis acid/base concept, which involves the donation or acceptance of electron pairs.
Lewis Acid/Base Concept:
According to the Lewis acid/base concept, an acid is a substance that can accept an electron pair, while a base is a substance that can donate an electron pair. In this concept, acids are referred to as electron pair acceptors (Lewis acids), and bases are referred to as electron pair donors (Lewis bases).
Explanation of Assertion A:
The amphoteric nature of water can indeed be explained by using the Lewis acid/base concept. Water can act as a Lewis acid by accepting an electron pair from a Lewis base, and it can also act as a Lewis base by donating an electron pair to a Lewis acid.
Explanation of Reason R:
The Reason R states that water acts as an acid with NH3 (ammonia) and as a base with H2S (hydrogen sulfide). This statement is true. Water can act as an acid when it donates a proton (H+) to ammonia (NH3), and it can act as a base when it accepts a proton from hydrogen sulfide (H2S).
Conclusion:
From the above explanation, we can conclude that Assertion A is false because the amphoteric nature of water is not solely explained by using the Lewis acid/base concept. However, Reason R is true as water can act as an acid with NH3 and as a base with H2S. Therefore, the correct answer is option D: A is false, but R is true.
Reason R: Water acts as an acid with NH3 and as a base with H2S.
