CO2+Ca(OH)2->CaCO3+H2O
1-----------1-------------1--------1
0,132----0,132---0,132----0,132
n CO2=\(\dfrac{3,36}{22,4}\)=0,15 mol
n CaCO3=0,132 mol
Lập tỉ lệ :
=>CO2 dư
=>VCa(OH)2=0,132 l=132ml
ta có:n caso3= 13.2 :120=0.11(mol) < n so2=3.36:22.4=0.15(mol) => so2 dư
bt "S" ta có n Ca(HSO3)2=(0.15-0.11):2=0.02(mol)
bt"Ca" ta có n Ca(oh)2 =0.02+0.11=0.13(mol)
=>V=0.13:1=0.13(lít)
