Carbonic acid (h2co3) is a solution of carbon dioxide in water. molecules of carbonic acid are not stable. the mixture of carbon dioxide and water ionizes stepwise: co2 + h2o h+ + hco3- hco3- co32- + h+ use the equations to explain the process of dynamic equilibrium and the equilibrium constant. according to lechatelier’s principle, what do you think would happen if after beginning the reaction with carbon dioxide and water, more carbon dioxide molecules were added to the system.
