Question

Show the stepwise dissociation of a diprotic acid, H₂CO₃, and the corresponding equilibrium equations.

Accepted Answer

H₂CO₃ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + HCO₃⁻ (aq);
K_a1 = ( [H₃O⁺] [HCO₃⁻] ) / [H₂CO₃]

HCO₃⁻ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq);
K_a2 = ( [H₃O⁺] [CO₃²⁻] ) / [HCO³⁻]

Answer

H₂CO₃ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + HCO₃⁻ (aq);
K_a1 = ( [H₃O⁺] [HCO₃⁻] ) / ( [H₂CO₃] [H₂O] )

HCO₃⁻ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq);
K_a2 = ( [H₃O⁺] [CO₃²⁻] ) / ( [HCO³⁻] [H₂O] )

Answer

H₂CO₃ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + HCO₃⁻ (aq);
K_a1 = [H₂CO₃] / ( [H₃O⁺] [HCO₃⁻] )

HCO₃⁻ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq);
K_a2 = [HCO³⁻] / ( [H₃O⁺] [CO₃²⁻] )

Answer

H₂CO₃ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + HCO₃⁻ (aq);
K_a1 = ( [H₂CO₃] [H₂O] ) / ( [H₃O⁺] [HCO₃⁻] )

HCO₃⁻ (aq) + H₂O (l) ⇌ H₃O⁺ (aq) + CO₃²⁻ (aq);
K_a2 = ( [HCO³⁻] [H₂O] ) / ( [H₃O⁺] [CO₃²⁻] )
