NaOH=Na+ + OH-
CuCl2= Cu2+ + 2Cl-
H2SO4= 2H+ + SO42-
или
1 ступень: H2SO4= H+ + HSO4-
2 ступень: HSO4- = H+ + SO42-
Ba(OH)2= Ba2+ + 2OH-
Al2(SO4)3= 2Al3+ + 3SO42-
1.CuCl2+2NaOH = Сu(OH)2↓ + 2NaCl
Cu(2+) + 2Cl(-) + 2Na(+) + 2OH(-) = Cu(OH)2 + 2Na(+) + 2Cl(-)
Cu(2+) + 2OH(-) = Cu(OH)2
2. 2NaOH + H2SO4 = Na2SO4 + 2H2O
2Na (+) + 2OH(-) + 2H(+) +SO4(2-) = 2Na(+) + SO4(2-) + 2H2O
2OH(-) + 2H(+) = 2H2O
OH(-) + H(+) = H2O
3. Al₂(SO₄)₃ + 6NaOH = 2Al(OH)₃↓ + 3Na₂SO₄
2Al⁺³ + 3SO₄²⁻ + 5Na⁺ + 6OH⁻ = 2Al(OH)₃↓ + 6Na⁺ + 3SO₄²⁻
2Al⁺³ + 6OH⁻ = 2Al(OH)₃↓
Al⁺³ + 3OH⁻ = Al(OH)₃↓
4. K2O+2HNO3=2KNO3+H2O
K2O + 2H+ + 2NO3- =2K+ + 2NO3- +H2O
K2O + 2H+ = 2K+ + H2O
5. ZnCl2+2AgNO3=Zn(NO3)2+2AgCl
Zn(2+) + 2Cl(-) + 2Ag(+) + 2NO3(-) = Zn(2+) + 2NO3(-) + 2AgCl
2Ag(+) + 2Cl(-) = 2AgCl
Ag+ + Cl- = AgCl
