Question

Identify conjugate acid and conjugate base for \(\mathrm{HCO_3^-}\) ion respectively.

• A. \(\mathrm{CO_3^{2-}}\) and \(\mathrm{H_2CO_3}\)
• B. \(\mathrm{H_2CO_3}\) and \(\mathrm{CO_3^{2-}}\)
• C. \(\mathrm{CO_2}\) and \(\mathrm{H_2CO_3}\)
• D. \(\mathrm{H_2CO_3}\) and \(\mathrm{CO^-}\)

Hint:

Remember: \[ \text{Conjugate Acid} = \text{Add } H^+ \] \[ \text{Conjugate Base} = \text{Remove } H^+ \] This shortcut works for all Brønsted acids and bases.
