Answer 1

Answer #1

2. An amphoteric compound can act as an acid as well as a base. An acid is a proton donor and a base is a proton acceptor.

In KHC2O4 the amphoteric behaviour can be expressed with following equation:

Functioning as acid:

HC₂O₄^- + H₂O ----- H₃O⁺ + C₂O₄^2-

Functioning as base:

HC₂O₄^- + H₂O ----- OH^- + H₂C₂O₄
