\(n_{SO_2}=\dfrac{2,24}{22,4}=0,1\left(mol\right);n_{NaOH}=1.0,15=0,15\left(mol\right)\\ Vì:1< \dfrac{n_{NaOH}}{n_{SO_2}}=\dfrac{0,15}{0,1}=1,5< 2\\ \Rightarrow Sp:Na_2SO_3,NaHSO_3\\ PTHH:2NaOH+SO_2\rightarrow Na_2SO_3+H_2O\left(1\right)\\ NaOH+SO_2\rightarrow NaHSO_3\left(2\right)\\ Đặt:n_{NaOH\left(1\right)}=a\left(mol\right);n_{NaOH\left(2\right)}=b\left(mol\right)\left(a,b>0\right)\\ \Rightarrow\left\{{}\begin{matrix}a+b=0,15\\0,5a+b=0,1\end{matrix}\right.\Leftrightarrow\left\{{}\begin{matrix}a=0,1\\b=0,05\end{matrix}\right.\\ \Rightarrow m_{muối}=0,5.a.126+b.104=11,5\left(g\right)\)
