NaCl→HCl→KCl→Cl2→NaCl→H2→HCl→Cl2→CuCl2→Cu(OH)2→CuSO4

Question

Hoàn thành các phương trình, chuỗi phản ứng sau:

NaCl→HCl→KCl→Cl2→NaCl→H2→HCl→Cl2→CuCl2→Cu(OH)2→CuSO4

Answer 1

NaCl + H2SO4 --> NaHSO4 + HCl

HCl + KOH --> KCl + H2O

2KCl + 2H2O --> 2KOH + Cl2 + H2 (đpdd cmn)

Cl2 + 2NaOH --> NaCl + NaClO + H2O

2NaCl + 2H2O --> 2NaOH + Cl2 + H2

H2 + Cl2 --> 2HCl 

4HCl + MnO2 --> MnCl2 + Cl2 + H2O

Cl2 + Cu --> CuCl2

CuCl2 + 2NaOH --> 2NaCl + Cu(OH)2

Cu(OH)2 + H2SO4 --> CuSO4 + 2H2O
