\(n_{SO_2}=\dfrac{5.6}{22.4}=0.25\left(mol\right)\)
TH1 : Tạo ra muối trung hòa
\(Ca\left(OH\right)_2+SO_2\rightarrow CaSO_3+H_2O\)
\(0.25...........0.25\)
\(C_{M_{Ca\left(OH\right)_2}}=\dfrac{0.25}{0.1}=2.5\left(M\right)\)
TH2 : Tạo ra muối axit
\(Ca\left(OH\right)_2+2SO_2\rightarrow Ca\left(HSO_3\right)_2\)
\(0.125............0.25\)
\(C_{M_{Ca\left(OH\right)_2}}=\dfrac{0.125}{0.1}=1.25\left(M\right)\)
