NaKCO3 (1 Viewer)

To show the amphiprotic ion HCO3- acting as a base, I wrote the following (incorrect) reaction in my chem exam - for which I lost a mark for.

NaHCO3 + KOH -> NaKCO3 + H2O

I admit that this wasn't the best example to show the HCO3- ion accepting a proton.

Can anyone suggest another reaction

HCO₃^- + H₂O <=> H₂CO₃ + OH^-

but of course
it was so simple
