Question #94580

Answer 1

a.) `F^-`(aq)
b.) is `CO_3^(2-)`

Explanation:

A conjugate base is an acid that has lost it's proton. So;

in a.)

HF is the acid and the proton goes from the acid to the water. Thus means the conjugate base is the `F^-`(aq) ion left over.

in b.) THANKS TO ANOR277 FOR THE CORRECTION
the conjugate base of bicarbonate ion, `HCO_3^(-)`, is `CO_3^(2-)`; its conjugate acid is `H_2CO_3`...
