Hoàn thành các chuỗi biến hóa sau :
HCl Cl2 FeCl3 NaCl AgCl
KMnO4 Cl2 HCl FeCl2 FeCl3 AgCl Cl2 Br2

Answer 1

[B.Thị Anh Thơ]

a)

\(4HCl+MnO_2\rightarrow MnCl_2+Cl_2+2H_2O\)

\(2Fe+3Cl_2\rightarrow2FeCl_3\)

\(FeCl_3+3NaOH\rightarrow3NaCl+Fe\left(OH\right)_3\)

\(NaCl+AgNO_3\rightarrow NaNO_3+AgCl\)

b)

\(2KMnO_4+16HCl\rightarrow2KCl+2MnCl2+5Cl_2+8H_2O\)

\(Cl_2+H_2\rightarrow2HCl\)

\(Fe+2HCl\rightarrow FeCl_2+H_2\)

\(2FeCl_2+Cl_2\rightarrow2FeCl_3\)

\(FeCl_3+3AgNO_3\rightarrow Fe\left(NO_3\right)_3+3AgCl\)

\(2AgCl\rightarrow2Ag+Cl_2\)

\(Cl_2+2NaBr\rightarrow2NaCl+Br_2\)
