Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula K N O 2. It is an ionic salt of potassium ions K + and nitrite ions NO 2−, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. [1]

2009年7月22日 · Potassium nitrite is an inorganic molecular entity and an inorganic potassium salt. It has a role as an antimicrobial food preservative and an antihypertensive agent. Potassium nitrite is a chemical compound of potassium and nitrite ions. It is used as a food preservative and in the manufacturing of heat transfer salts.

Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is a potassium salt of nitric acid. This salt consists of potassium cations K+ and nitrate anions NO− 3, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [5] .

Potassium nitrite represented by the chemical formula KNO 2 is a yellowish white crystalline and deliquescent powder that is soluble in water, alcohol and liquid ammonia [1]. It is a potassium salt and an ionic compound [1, 3].

Calculate the pH of a 0.35 M solution of KNO 2 (Ka = 4.0 x 10 -4). KNO 2 is a salt of a strong base KOH and a weak acid HNO 2 and therefore, the solution will be basic. Dissociate the salt and write the reaction of its weak component with water. KNO 2 → K + + NO 2–. NO 2– (aq) + H 2 O (l) → HNO 2 (aq) + OH– (aq) (basic)
