The amount of carbon dioxide in a gaseous mixture of CO2 and CO can be determined by passing the gas into an aqueous solution that contains an excess of Ba(OH)2, The CO2 reacts, yielding a precipitate of BaCO3, but eh CO does not react. This method was used to analyze the equilibrium compostion of the gas obtained when 1.77 g of CO2 reacted with 2.0 g of graphite in a 1.000 L container at 1100 K. The analysis yielded 3.41...
