Question

A solution of carbonic acid, H₂CO3(aq), is at equilibrium. How would thesystem change if more carbonic acid were added to the solution?A. More H and HCO3 would be produced.B. More H and less HCO3 would be produced.C. Less H and HCO3 would be produced.D. Less H and more HCO3 would be produced.

Answer 1

A. More H⁺ and HCO₃⁻ would be produced.

Step-by-step explanation

A solution of carbonic acid, H₂CO3(aq), at equilibrium is represented as shown below:

H₂CO₃(aq) ⇌ H⁺ (aq) + HCO₃⁻(aq)

The addition of more carbonic acid to the solution will shift the system to the right; that is, more H⁺ and HCO₃⁻ would be produced.
