Question

What are the conjugate base and conjugate acid for HSO4−? What is the term used to describe species that can behave as either an acid or a base, depending on the chemical environment?

Answer 1

Answer:

Conjugate acid- H^+

Conjugate base- SO4^2-

Terminology- Amphoteric

Explanation:

Consider the equilibrum shown below;

HSO4^-(aq)<-------> H^+(aq) + SO4^2-(aq)

Hence, When HSO4^- is dissolved in aqueous solution, it's conjugate acid is H^+ and it's conjugate base is SO4^2- as shown in the equation above.

If a substance behaves both as an acid and as a base, then the substance is Amphoteric in nature.

Answer 2

The conjugate acid $H^+$and base $SO4^2-$ and the term would be Amphoteric.

Conjugate acid-

What is Amphoteric?

Amphoteric is described as the term employed to denote a substance that possesses the characteristics of both an acid, as well as, a base.

Given equilibrium:

$HSO4^-(aq)$ → $H^+(aq) + SO4^2-(aq)$

Therefore, the dissolution of $HSO4^-$ in water leads to the display acid that is conjugate $H^+$ and the conugate base $SO4^2-$.

In case, the properties of both are reflected, it shows amphoteric nature.
