| Which of the listed substances will the copper chloride solution 2 react with: silver nitrate, sodium chloride, iron, phosphoric acid, zinc oxide, potassium hydroxide? Write the molecular and ionic equations of possible reactions.
А).
СuCl2 + 2AgNO3 = 2AgCl↓ + Cu(NO3)2.
Сu2+ + 2Cl1- + 2Ag1+ + 2NO31- = 2AgCl↓ + Cu 2++ 2NO31-.
2Ag1+ + 2Cl1- = 2AgCl↓.
Б).
СuCl2 + Fe = FeCl2 + Cu↓.
Сu2+ + 2Cl1-+ Fe0 = Fe2+ + 2Cl + Cu0↓.
Сu2+ + Fe0 = Fe2+ + Cu0↓.
В).
3СuCl2 +2H3PO4 = Cu3(PO4)2 ↓+ 6HCl.
3Сu2+ + 2Cl 1-+6H1+ +2PO43- = Cu3(PO4)2 ↓+ 6H1+ + 6Cl1-.
3Сu2+ + 2PO43- = Cu3(PO4)2 ↓.
Г).
СuCl2 + 2KOH = Cu(OH)2 ↓ + 2KCl.
Сu2+ + 2Cl1- + 2K1+ + 2OH1- = Cu(OH)2 ↓ + 2K1+ + 2Cl1-.
Сu2+ + 2OH1- = Cu(OH)2 ↓.
