Cu2+ + e- => Cu+ Reduction

SO2 + 2 H2O => SO4 2- + 4 H+ + 2 e- Oxidation

KGV = 2

2 Cu2+ + 2 e- => 2 Cu+

2 Cu2++ SO2 + 2 H2O => 2 Cu+ + SO4 2- + 4 H+

Addition of sulfate

2 CuSO4 + SO2 + 2 H2O => 2 Cu+ + 3 SO4 2- + 4 H+

Addition of NaCl

2 CuSO4 + SO2 + 2 H2O + 2 NaCl => 2 CuCl + NaS2O4 +H2SO4

Addo f the crystall water reduce the water

2 CuSO4 x 5 H2O + SO2 + 2 NaCl => 2 CuCl + Na2SO4 + 2 H2SO4 + 3 H2O

finished

Correction

2 CuSO4 + SO2 + 2 H2O + 2 NaCl => 2 CuCl + Na2SO4 + 2 H2SO4
