SO2 + 2NaOH--> Na2SO3 + H2O
CO2 + 2NaOH--> Na2CO3 + H2O
Gọi nSO2=a mol ; nCO2=b mol
Ta có a+ b=8,96/22,4=0,4 mol
Theo PTHH ta có:
m muối= mNa2SO3 + mNa2CO3=126a + 106b=48,4g
=>a=0,3 mol ; b=0,1 mol
%VSO2=0,3.100/(0,3+0,1)=75%
=> %V CO2=100-75=25%
%mSO2=0,3.64.100/(0,3.64+0,4.44)=52,17%
%mCO2=100-52,17=47,83%
nhh khí = 8,96: 22,4=0,4 mol
