What happens when we put sodium hydroxide in water, copper chloride in water and then mix them? Cl -1 Na+1 OH -1 Cu+2 Cl -1 Sodium Hydroxide (NaOH) Copper Chloride (CuCl2) NOT BALANCED

Na(OH)(aq) + CuCl2(aq) Cl -1 Na+1 OH -1 Cu+2 Cl -1 NOT BALANCED

Na(OH)(aq) + CuCl2(aq) Cl -1 Na+1 OH -1 Cu+2 Cl -1

Na(OH)(aq) + CuCl2(aq) Cl -1 Na+1 OH -1 Cu+2 Cl -1

Na(OH)(aq) + CuCl2(aq) Cl -1 Na+1 OH -1 Cu+2 Cl -1

Na(OH)(aq) + CuCl2(aq) dissociation aq = aqueous Na+1 Cu+2 Cl -1 OH -1

WHAT HAPPENS WHEN YOU COMBINE THEM? Na(OH)(aq) + CuCl2(aq) WHAT HAPPENS WHEN YOU COMBINE THEM? Na+1 Cu+2 Cl -1 OH -1 Cl -1

WHAT HAPPENS WHEN YOU COMBINE THEM? Na(OH)(aq) + CuCl2(aq) WHAT HAPPENS WHEN YOU COMBINE THEM? Na+1 OH -1 Cu+2 Cl -1

Na(OH)(aq) + CuCl2(aq) Cl -1 Cu+2 Na+1 OH -1 Cl -1

Na(OH)(aq) + CuCl2(aq)  NaCl(aq) + Cu(OH)2 (s) The Copper cation and Hydroxide anion are attracted to one another more than the water molecules so they are going to join). Cl -1 Cu+2 Na+1 OH -1 Cl -1

Na(OH)(aq) + CuCl2(aq)  NaCl(aq) + Cu(OH)2 (s)

Na(OH)(aq) + CuCl2(aq)  NaCl(aq) + Cu(OH)2 (s) The Copper and Hydroxide Join to form solid Copper Hydroxide Cl -1 Na+1 Cu+2 OH -1 Precipitate Cl -1 Equation Not Balanced

Na(OH)(aq) + CuCl2(aq)  NaCl(aq) + Cu(OH)2 (s) The Copper and Hydroxide Join to form solid Copper Hydroxide Cl -1 Na+1 Cu+2 OH -1 Precipitate OH -1 Cl -1 Equation Not Balanced

2Na(OH)(aq) + CuCl2(aq)  2NaCl(aq) + Cu(OH)2 (s)
