\(2Cl2+6KOH-->3H2O+5KCl+KCLO3\)
\(n_{Cl2}=\frac{1,12}{22,4}=0,05\left(mol\right)\)
\(n_{KOH}=0,2.1,6=0,32\left(mol\right)\)
Lập tỉ lệ
\(n_{Cl2}\left(\frac{0,05}{3}\right)< n_{KOH}\left(\frac{0,32}{6}\right)=>KOHdư\)
dd X gồm KCl và KOH dư
\(n_{KOH}=2n_{Cl2}=0,1\left(mol\right)\)
\(C_{M\left(KOH\right)dư}=\frac{0,1}{0,2}=0,5\left(M\right)\)
\(n_{KCl}=\frac{5}{3}n_{Cl2}=\frac{1}{12}\left(mol\right)\)
\(C_{M\left(KCl\right)}=\frac{1}{12}:0,2=\frac{5}{12}\left(M\right)\)
