Re: Amphoteric HCO3
An acid is a proton donator, a base is a proton acceptor. Work with this.
And its HCO3-

Re: Amphoteric HCO3
HCO3⁻ + H2O → H3O⁺ + CO3⁻² Hydrogen carbonate anion acts as an acid.
\(HCO_3^- + H_2O \rightarrow H_2CO_3 + OH^- \) Hydrogen carbonate anion acts as an base
\(HCO_3^- + H_2O \rightarrow H_2CO_3 + OH^- \) Hydrogen carbonate anion acts as an base
