Chapter 15, Problem 7E

Interpretation Introduction

Interpretation:

${\text{H}}_2{\text{PO}}_4^{-}$ is given to possess an amphoteric nature. The equations that show both its acidic and basic nature in an aqueous solution are to be stated.

Concept introduction: Amphoteric compounds are those compounds which show acidic as well as basic behavior. Acid is that species which donates ${\text{H}}^{+}$ ions.

Base is that species which donates ${\text{OH}}^{-}$ ions.

To determine: The equations that show both the acidic and basic nature of ${\text{H}}_2{\text{PO}}_4^{-}$ .
