\(PTHH:Na_2SO_3+2HCl\rightarrow2NaCl+H_2O+SO_2\uparrow\\ K_2SO_3+2HCl\rightarrow2KCl+H_2O+SO_2\uparrow\\ n_{SO_2}=\dfrac{4,48}{22,4}=0,2\left(mol\right)\\ \Rightarrow\left\{{}\begin{matrix}n_{Na_2SO_3}+n_{K_2SO_3}=0,2\\126n_{Na_2SO_3}+158n_{K_2SO_3}=28,4\end{matrix}\right.\\ \Rightarrow\left\{{}\begin{matrix}n_{Na_2SO_3}=0,1\left(mol\right)\\n_{K_2SO_3}=0,1\left(mol\right)\end{matrix}\right.\)
\(\Rightarrow\%_{m_{Na_2SO_3}}=\dfrac{0,1\cdot126}{28,4}\cdot100\%\approx44\%\\ \Rightarrow\%_{m_{K_2SO_3}}=100\%-44\%=56\%\)
\(n_{HCl}=0,1\cdot2+0,1\cdot2=0,4\left(mol\right)\\ \Rightarrow m_{CT_{HCl}}=0,4\cdot36,5=14,6\left(g\right)\\ \Rightarrow C\%_{HCl}=\dfrac{14,6}{200}\cdot100\%=7,3\%CC\)
