Question

What is the difference between displacement and double displacement reactions? Write equations for these reactions.

Hint:

Double displacement reactions often result in the formation of a precipitate.

Answer 1

Difference:
- Displacement Reaction: A more reactive element replaces a less reactive one in a compound.
- Double Displacement Reaction: Exchange of ions occurs between two compounds to form new products.
Examples: \[ \text{Displacement: } CuSO_4 + Zn \rightarrow ZnSO_4 + Cu \] \[ \text{Double Displacement: } NaCl + AgNO_3 \rightarrow AgCl + NaNO_3 \]
