Conjugate acid-base pairs

Monobasic acids

• donates one proton per molecule in an acid-base reaction

• HCl, HNO3, HCOOH

• note 3rd ionic equation should be 2H^+ + MgO -> Mg^2+ + H2O as MgO is solid

Conjugate acid-base pairs

• two species that can be interconverted by transfer of a proton

• hydronium ion - H3O^+

•
