Đáp án:
2KMnO4 + 16HClđ $\buildrel{{t^o}}\over\longrightarrow$ 2KCl + 2MnCl2 +5Cl2 + 8H2O
Cl2 + H2 $\buildrel{{as}}\over\longrightarrow$ 2HCl
6HCl + Fe2O3 --> 2FeCl3 + 3H2O
FeCl3 +3 NaOH --> Fe(OH)3 + 3NaCl
2NaCl $\buildrel{{đpnc}}\over\longrightarrow$ 2Na +Cl2
3Cl2 + 6KOHđ $\buildrel{{100^oC}}\over\longrightarrow$ KClO3 + 5KCl +3 H2O
KClO3 +6 HClđ $\buildrel{{t^o}}\over\longrightarrow$ KCl + 3Cl2 + 3H2O
2KCl(tt)+ H2SO4đ $\buildrel{{t^o}}\over\longrightarrow$ K2SO4 + 2HCl
