Question

"$HC{O}_3^{-}$ is amphoteric."
Answer whether the above statement is true or false.
If true enter 1, else enter 0.

Answer 1

"$HC{O}_3^{-}$ is amphoteric."as it can act as acid as well as base.

The bicarbonate ion $\left(HC{O}_3^{-}\right)$ can either donate a proton (acid) to form the carbonate ion $\left(C{O}_3^{-2}\right)$ or it can accept a proton (base) to form carbonic acid $\left(H_{2}C{O}_3\right)$.
