Question

Which one of the following reactions is not an example of redox reaction? (A) Cl2 + 2H2O + SO2 → 4H+ + SO4- 2Cl- (B) Cu++ + Zn → Zn++ + Cu (C) 2H2 + O2 → 2H2O (D) HCl + H2O → H3O- + Cl-

In reaction HCl + H2O → H3O + Cl-, only reduction has taken place not oxidation

Q. Which one of the following reactions is not an example of redox reaction?

$C l_{2} + 2 H_{2} O + S O_{2} \to 4 H^{+} + S O^{4 -} 2 C l^{-}$

$C u^{++} + Z n \to Z n^{++} + C u$

$2 H_{2} + O_{2} \to 2 H_{2} O$

$H Cl + H_{2} O \to H_{3} O^{-} + C l^{-}$

In reaction $H Cl + H_{2} O \to H_{3} O + C l^{-}$ , only reduction has taken place not oxidation

Q. Which one of the following reactions is not an example of redox reaction?

Cl2​+2H2​O+SO2​→4H++SO4−2Cl−

Cu+++Zn→Zn+++Cu

2H2​+O2​→2H2​O

HCl+H2​O→H3​O−+Cl−

In reaction HCl+H2​O→H3​O+Cl−, only reduction has taken place not oxidation

$C l_{2} + 2 H_{2} O + S O_{2} \to 4 H^{+} + S O^{4 -} 2 C l^{-}$

$C u^{++} + Z n \to Z n^{++} + C u$

$2 H_{2} + O_{2} \to 2 H_{2} O$

$H Cl + H_{2} O \to H_{3} O^{-} + C l^{-}$

In reaction $H Cl + H_{2} O \to H_{3} O + C l^{-}$ , only reduction has taken place not oxidation
