Three examples of double displacement reactions:
- Reaction Between Sodium Chloride and Silver Nitrate: NaCl+AgNO3→NaNO3+AgCl
- Explanation: Sodium chloride (NaCl) reacts with silver nitrate (AgNO3_33​) to form sodium nitrate (NaNO3_33​) and silver chloride (AgCl), which is a white precipitate.
- Reaction Between Barium Chloride and Sodium Sulfate: BaCl2+Na2SO4→BaSO4+2NaCl
- Explanation: Barium chloride (BaCl2​) reacts with sodium sulfate (Na2​SO4​) to form barium sulfate (BaSO4​), which is a white precipitate, and sodium chloride (NaCl).
- Reaction Between Potassium Iodide and Lead(II) Nitrate: 2KI+Pb(NO3)2→PbI2+2KNO3
- Explanation: Potassium iodide (KI) reacts with lead(II) nitrate (Pb(NO3​)2) to form lead(II) iodide (PbI2​), which is a yellow precipitate, and potassium nitrate (KNO3​).
