Determine the partial pressure of CO2 corresponding the transition between solid phases of Mg(OH)2(S) and magnesite MgCO3(S) in an open system open to CO2. Which solid phase will predominate at a 10-3.5 Atm pressure of CO2? The solubility products of Mg(OH)2 and MgCO3 are 10-10.7 and 10-7.5, respectively. The Henry constant of CO2 is 101.5 Atm·L·mol-1
