Os + 3KNO₃ + 2KOH = K₂OsO₄ + 3KNO₂ + H₂O
Os + 8OH⁻ - 6e= OsO₄²⁻ + 4H₂O |1
NO₃⁻ + H₂O + 2e = NO₂⁻ + + 2OH⁻ |3
-----------------------------------------------------------
Os + 8OH⁻ + 3NO₃⁻ + 3H₂O = OsO₄²⁻ + 4H₂O + 3NO₂⁻ + 6OH⁻
Os + 2OH⁻ + 3NO₃ ⁻ = OsO₄²⁻ + H₂O + 3NO₂⁻
Os - восстановитель
KNO₃ - окислитель
