Налейте в пробирку 1—2 мл концентрированного раствора серной кислоты и опустите в нее кусочек цинка. составьте уравнение реакции в молекулярном, ионном и сокращенном ионном виде, покажите переход электронов. что в этой реакции является окислителем?
Zn⁰ - 2e⁻ = Zn²⁺ | 4 восстановитель
S⁶⁺ + 8e⁻= S²⁻ | 1 окислитель
4Zn⁰+10H⁺+5SO₄=4Zn²⁺+4SO₄²⁻+H₂S+4H₂O
Zn⁰ + 10H⁺ + SO₄ = Zn²⁺+H₂S + 4H₂O
