Problem

A laboratory buffer contains significant amounts of both

\mathrm{CO_3^{2-}}(aq)

and

\mathrm{HCO_3^-}(aq)

. An aliquot supplies exactly

2.0\,\text{mmol}

H_3O^+

250\,\text{mL}

of this buffer. Write the complete sequence of balanced net ionic reaction(s) that occur as the buffer neutralizes all of the added

H_3O^+

ions.
