Consider this reaction: NH4 HPO42− → NH3 H2PO4− Which is the Bronsted-Lowry acid ? NH4 HPO42- HPO42– H2PO4–.
kvv77 [185]

Bronsted - Lowry acid in the given reaction is NH₄, as it gives H⁺ ion.

<h3>What is Bronsted - Lowry acid?</h3>

According to the theory of Bronsted - Lowry, acids are those substances which gives H⁺ ion or proton in the aqueous medium.

Given chemical reaction is :

NH₄ + HPO₄²⁻ → NH₃ + H₂PO₄⁻

In the above reaction NH₄ is the Bronsted - Lowry acid as it gives H⁺ ion in the reaction and changes to NH₃ which is the conjugate base of NH₄. Whereas HPO₄²⁻ is the  Bronsted - Lowry base as it accepts the H⁺ ion to form H₂PO₄⁻ which is the conjugate acid of it.

Hence, option (1) is correct, i.e. NH₄ is the Bronsted - Lowry acid.

An element A forms a compound AH3 with hydrogen. Another element B forms a compound BA2 with B. Given that the valency of hydrog
Hatshy [7]

Answer:

A - 3

B - 6

Explanation:

The valency of hydrogen atom is +1

The valancy of an atom of other element combining with the hydrogen atom can be determined from the  number of associated hydrogen.

when H combines with A, three atoms of hydrogen are used. Thus the valency of element A is -3

Now B combines with two molecules of A whose valency is -3

The valency of B would be twice the valency of element A i.e 6

if hydrogen combines with B, then the compound formed will be BH6
