Redox Reactions

Which reaction is not a redox reaction?

A. $2KCl O_{3} + I_{2} \to 2KI O_{3} + C l_{2}$
B. $H_{2} + C l_{2} \to 2HCl$
C. $BaC l_{2} + N a_{2} S O_{4} \to BaS O_{4} + 2NaCl$ ✓
D. $Zn + CuS O_{4} \to ZnS O_{4} + Cu$

Solution

$BaC l_{2} + N a_{2} S O_{4} \to BaS O_{4} + 2NaCl$ is a double displacement (precipitation) with no change in any oxidation number. The other three involve electron transfer.
