\(n_{SO_2}=\dfrac{1.12}{22.4}=0.05\left(mol\right)\)
\(n_{NaOH}=0.05\cdot1=0.05\left(mol\right)\)
\(\dfrac{n_{NaOH}}{n_{SO_2}}=\dfrac{0.05}{0.05}=1\)
\(X:NaHSO_3\)
\(n_{SO_2} = \dfrac{1,12}{22,4} = 0,05(mol)\\ n_{NaOH} =0,05.1 = 0,05\\ \text{Ta có : }\\ \dfrac{n_{NaOH}}{n_{SO_2}} = \dfrac{0,05}{0,05} = 1\)
Do đó, dung dịch X chỉ chứa muối NaHSO3
\(NaOH +S O_2 \to NaHSO_3\)
