Which of the following is a redox reaction?
A$NaOH + HCl \rightarrow NaCl + H_2O$
B$BaCl_2 + H_2SO_4 \rightarrow BaSO_4 + 2HCl$
C$Zn + CuSO_4 \rightarrow ZnSO_4 + Cu$
D$CaCO_3 \rightarrow CaO + CO_2$
✓ Correct Answer: C — $Zn + CuSO_4 \rightarrow ZnSO_4 + Cu$
In this displacement reaction, Zn is oxidized and Cu is reduced, which constitutes a redox process.
