Conjugate Acid–Base Pairs
Write the formula of the conjugate base of each of the following:
a. {\mathrm{HBrO}}_{3} b. {\mathrm{HCO}}_{3}^-
a. When {\mathrm{HBrO}}_{3} loses \mathrm{H}^{+} ,it forms its conjugate base \mathrm{BrO_{3}}^{-} .
b. When {\mathrm{HCO}}_{3}^- loses \mathrm{H}^{+} ,it forms its conjugate base \mathrm{CO_{3}}^{2-} .
