1). You place a beaker containing 1kg of water in contact with an atmosphere that has a CO2 partial pressure of 102.5atm and you allow free exchange of gas until equilibrium is established (remember KH=101.5 ), then you cap the solution and change the pH by titration. There is no subsequent exchange of gas with the atmosphere. Please answer the following questions about the solution speciation: a) What is the mass balance equation for dissolved carbonate? Is this a closed or open system? b) What is the total carbonate concentration (SCO3 or CT) as a function of pH or [H+] ? c) Write the equation for the concentration of CO32 as a function of pH or [H+] ? d) Please give me an equation for the partial pressure of CO2 in this solution as a function of pH. *Hint* start with the concentration of H2CO3 as a function of pH or [H+]
