2 g of impure CaCO3 reacts with HCI to produce 410 mL of CO2 at 1 atmospheric pressure and 27°C. Calculate the percentage purity of the CaCO3 used. 2 g of impure CaCO3 reacts with HCI to produce 410 mL of CO2 at 1 atmospheric pressure and 27°C. Calculate the percentage purity of the CaCO3 used.
Firstly we convert volume of CO2 at STP.1×410/300 = 1×V/273or, V = 373.1 mLWe know at STP22400 ml of CO2 weighs 44 gSo, 373.1 mL of CO2 weighs (44×373.1)/22400or weight of CO2 is 0.732875 g.Now we apply POAC on 'C':1×x/100= 1×0.732875/44or x=1.665625 gSo, percentage purity of CaCO3 is = 1.665625/2 ×100=83.28 %or x=1.665625 gSo percentage of
