Now,
Cu→Cu
2+
+2e
−
⟶(1)
NO
3
−
+4H
+
+3e
−
⟶NO+2H
2
O⟶(2)
Equation (1) ×3+ Equation (2) ×2 (for equalising electrons)
3Cu⟶3Cu
2+
+6e
−
2NO

−
+8H
+
+6e
−
⟶2NO+4H
2
O
___________________________________
3Cu+2NO

−
+8H
+
⟶3Cu
2+
+2NO+4H
2
O
But 8H
+
+8NO
3
−
⟶8HNO
3
The 6 NO
3
2−
combine with Cu
2+
∴ Balanced equation is,
3Cu+8HNO
3
⟶3Cu(NO
