Ocean Acidification
« on: June 23, 2020, 09:13:15 AM »
Hi, so i need some clarification on how Le Chatilier's Principle will affect the following equations

H2CO3  ::equil::  H++HCO3-
HCO3- ::equil::  H++CO32-

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)
