The Equation Shown Here Is the Net Reaction That Occurs $\rarr$

The equation shown here is the net reaction that occurs when a strong acid is added to a CO₃^2-/HCO₃^- buffer solution (for carbonic acid, K_a1 = 4.2 * 10^-7, K_a2 = 2.4 * 10^-8): CO₃^2- + H⁺ $\rarr$ HCO₃^- and HCO₃^- + H⁺ $\rarr$ H₂CO₃
