Chemistry

The pH of earth's water is controlled by the combination ofseveral equilibria found in water, as well as between water and theatmosphere. This problem considers a model for oceanic water. H2CO3+ CO3 yields 2HCO3 1) Calculate the equilibrium constant for thisequilibrium using Ka1 and Ka2 of carbonic acid. 3) Starting from apure solution of HCO3, how are the concentrations of H2CO3 and CO3related to each other? 4) Ocean water has an average pH of approx.8.1. How are the concentrations of H2CO3 and CO3 related to eachother in ocean water? 4) Do you think modeling ocean water as apure dilute bicarbonate ion solution a good model
