Hi, so i need some clarification on how Le Chatilier's Principle will affect the following equations

H₂CO₃    H⁺+HCO₃^-
HCO₃^-   H⁺+CO₃^2-

According to my textbook, if concentration of H₂CO₃ increases, both H⁺ and HCO₃^- increases. However, concentration of H⁺ increases more than HCO₃^- (and so on for the second equation).

What would happen if H₂CO₃^- decreases in concentration? Would concentration of H⁺ decrease more that HCO₃^-? And what would then happen to the second equation?

Le Chatelier's principle is rather poor way of dealing with complex equilibria. While you can try to predict some general behavior, exact answers require exact calculations.

Could you give a general conclusion of what would happen (since my syllabus does not require any calculations)
