Consider this reaction: h3bo3(aq) + hs-(aq) h2bo3-(aq) + h2s(aq) what is the sequence of brønsted-lowry acids and bases? a. base + acid acid + base b. acid + base acid + base c. acid + base base + acid d. base + acid base + acid

Answer : The correct option is (C).

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

The given equilibrium reaction will be,

In this reaction, is an acid that donate a proton or hydrogen to base and it forms and are conjugate base and acid respectively.

That means, and are acid and base and and are conjugate base and acid respectively.

The general sequence of Brønsted-Lowry acids and bases is:

From the given option we conclude that the correct sequence will be:

Hence, the correct option is (C)

we need the questions , i may then you.
