• HCI (base) / H₃O⁺ (conjugate acid)

Acid-base conjugate pairs differ by a single

• Electron

• Proton

• Neutron

• Oxygen

Which of the following show an acid and its conjugate base pair (in that order)

• H₂SO₄, SO₄^2-

• OH^-, H₂O

• NH₄⁺, H₂O

• H₂CO₃, HCO₃^-

Could CH₃COO^- act as a base when placed in water?

• Yes, because it can accept a H⁺

• Yes, because it can donate a H⁺

• No, because it cannot donate a H⁺

• No, because it cannot accept a H⁺
