Ion Exchange Reaction Equations

1. Potassium Hydroxide and Copper(II) Chloride: - Equation: 2KOH + CuCl2 = Cu(OH)2 + 2KCl - Ionic Equation: 2K+ + 2OH- + Cu2+ + 2Cl- = Cu(OH)2 + 2K+ + 2Cl-.

2. Sodium Carbonate and Hydrochloric Acid: - Equation: Na2CO3 + 2HCl = H2O + CO2 + 2NaCl - Ionic Equation: 2Na+ + CO3^2- + 2H+ + 2Cl- = H2O + CO2 + 2Na+ + 2Cl- [[1]](https://skysmart.ru/articles/chemistry/reakcii-obmena-i-himicheskie-uravneniya-dlya-nih).

3. Sodium Hydroxide and Hydrochloric Acid: - Equation: NaOH + HCl = H2O + NaCl - Ionic Equation: Na+ + OH- + H+ + Cl- = H2O + Na+ + Cl-.

4. Sodium Chloride and Lead(II) Nitrate: - Equation: 2NaCl + Pb(NO3)2 = PbCl2 + 2NaNO3 - Ionic Equation: 2Na+ + 2Cl- + Pb2+ + 2NO3- = PbCl2 + 2Na+ + 2NO3- [[1]](https://skysmart.ru/articles/chemistry/reakcii-obmena-i-himicheskie-uravneniya-dlya-nih).

5. Lead(II) Ion and Chloride Ion: - Ionic Equation: Pb2+ + 2Cl- = PbCl2.

These equations represent various ion exchange reactions involving different compounds and ions.
