The correct option is D I and IICorrosion of Copper gives Cu2-OH-2SO4 and Cu2-OH-2CO32Cu-H2O-SO3-O2-x2192-Cu2-OH-2SO42Cu2-H2O-CO2-O2-x2192-Cu2-OH-2CO3Option D is correct-

In an atmosphere with industrial smog, copper corrodes to:
I. $C u_{2} (O H)_{2} S O_{4}$
II. $C u_{2} (O H)_{2} C O_{3}$
III. $C u S O_{4}$
IV. $C u C O_{3}$
I and III
II and IV
I and IV
I and II

The correct option is D I and II
Corrosion of Copper gives $C u_{2} (O H)_{2} S O_{4}$ and $C u_{2} (O H)_{2} C O_{3}$

$2 C u + H_{2} O + S O_{3} + O_{2} \to C u_{2} (O H)_{2} S O_{4}$

$2 C u_{2} + H_{2} O + C O_{2} + O_{2} \to C u_{2} (O H)_{2} C O_{3}$

Option D is correct.

In an atmosphere with industrial smog, copper corrodes to:I. Cu2(OH)2SO4II. Cu2(OH)2CO3III. CuSO4IV. CuCO3I and IIIII and IVI and IVI and II

The correct option is D I and IICorrosion of Copper gives Cu2(OH)2SO4 and Cu2(OH)2CO32Cu+H2O+SO3+O2→Cu2(OH)2SO42Cu2+H2O+CO2+O2→Cu2(OH)2CO3Option D is correct.
