Nitrite is the conjugate base of the weak acid nitrous acid: . HNO 2 ⇌ H + + NO − 2; pK a ≈ 3.3 at 18 °C. Nitrous acid is also highly volatile – in the gas phase it exists predominantly as a trans-planar molecule. Meat processors cure meat using an ingredient containing sodium nitrite, and there are legal limits on the amount of nitrite allowed to be added in meats. Ham and whole muscle products are allowed to have 200 ppm of nitrite, sausage is allowed 156 ppm, and bacon is allowed 120 ppm.
