N₂⁺⁵O₅⁻²+2Na⁺O⁻²H=2Na⁺N⁺⁵O₃⁻²+H₂O не ОВР
4N⁺⁴O2+4NaOH+O2⁰=4NaN⁺⁵O3⁻²+2H2O
N⁺⁴ -e⁻ = N⁺⁵ | 4 восст-ль
O₂⁰-4e⁻=2O⁻² |1 ок-ль
3)
2Н₂⁺O⁻²=2H₂⁰+O₂⁰
2H⁺+2e⁻ = H₂⁰ | 2 ок-ль
2O⁻² - 4e⁻ = O₂⁰ | 1 в-ль
4)
3N₂⁺³O₃+H₂O=2HN⁺⁵O₃+4N⁺²O
2N⁺³ - 4e⁻=2N⁺⁵ | 2 в-ль
2N⁺³ + 2e⁻=2N⁺² | 1 ок-ль
5)
N₂⁺³O3+2NaOH=2NaN⁺³O2+H2O не ОВР
