Q. In a displacement reaction: Zn + CuSO₄ → ZnSO₄ + Cu, which statement is correct?

एक विस्थापन प्रतिक्रिया में: Zn + CuSO₄ → ZnSO₄ + Cu, कौन सा कथन सही है?

Copper is more reactive than zinc
तांबा जस्ता की तुलना में अधिक प्रतिक्रियाशील है

Zinc is more reactive than copper
जस्ता तांबे की तुलना में अधिक प्रतिक्रियाशील है

Both metals have equal reactivity
दोनों धातुओं की प्रतिक्रियाशीलता समान है

No reaction occurs
कोई प्रतिक्रिया नहीं होती

In the reaction: Zn + CuSO₄ → ZnSO₄ + Cu

This is a displacement reaction where zinc displaces copper from copper sulfate. This occurs because:

Zinc is higher in the reactivity series than copper

More reactive metals can displace less reactive metals from their compounds

Zinc loses electrons (oxidation): Zn → Zn²⁺ + 2e⁻

Copper gains electrons (reduction): Cu²⁺ + 2e⁻ → Cu

If copper were more reactive, the reaction would not proceed in this direction.
