Reactions in which Potassium nitrite is involved

  • 2{M}NO2 + H2SO4 -> {M}2SO4 + NO + NO2 + H2O , where M = Li Na K Rb
  • N2O3 + 2{M}OH -> 2{M}NO2 + H2O , where M = Na K Li Rb
  • NOF + 2{M}OH -> {M}NO2 + {M}F + H2O , where M = Na K Li Cs Rb
  • 4NOBr + 6{M}OH -> {M}NO3 + {M}NO2 + 2NO + 4{M}Br + 3H2O , where M = Na K Li Cs Rb
  • NOBF4 + 2{M}OH → {M}NO2 + {M}BF4 + H2O , where M = Na K
