\(n_{Ba\left(OH\right)_2}=0.2\cdot1.5=0.3\left(mol\right)\)
\(n_{KOH}=0.2\cdot1=0.2\left(mol\right)\)
\(n_{BaCO_3}=\dfrac{47.28}{197}=0.24\left(mol\right)\)
TH1 : Không tạo ra Ba(HCO3)2
Ba(OH)2 + CO2 -> BaCO3 + H2O
nCO2 = nBaCO3 = 0.24 (mol)
VCO2 = 0.24 x 22.4 = 5.376 (l)
TH2 : Tạo ra Ba(HCO3)2
KOH + CO2 -> KHCO3
0.2.........0.2
Ba(OH)2 + CO2 -> BaCO3 + H2O
0.24............0.24.........0.24
Ba(OH)2 + 2CO2 -> Ba(HCO3)2
0.3 - 0.24......0.12
nCO2 = 0.2 + 0.24 + 0.12 = 0.56 (mol)
VCO2 = 0.56 x 22.4 = 12.544 (l)
\(\Rightarrow5.376\le V_{CO_2}\le12.544\)
