Zapis cząsteczkowy i jonowy(tylko 3 przykłady):
a)CuSO₄+NaOH-->
b)Cu(NO₃)₂+CaS-->
c)CrCl₃+KOH-->
Dziękuję :)
a)CuSO₄ + 2NaOH--> Cu(OH)₂ + Na₂SO₄
Cu²⁺ + SO₄²⁻ + 2Na⁺ + 2OH⁻ -> Cu(OH)₂ + 2Na⁺ + SO₄²⁻
Cu²⁺ + 2OH⁻ -> Cu(OH)₂
b)Cu(NO₃)₂ + CaS--> CuS + Ca(NO₃)₂
Cu²⁺ + 2NO₃⁻ + Ca²⁺ + S⁻ -> CuS + Ca²⁺ + 2NO₃⁻
Cu²⁺ + S⁻ -> CuS
c)CrCl₃ + 3KOH--> Cr(OH)₃ + 3KCl
Cr³⁺ + 3Cl⁻ + 3K⁺ + 3OH⁻ -> Cr(OH)₃ + 3K⁺ + 3Cl⁻
Cr³⁺ + 3OH⁻ -> Cr(OH)₃
