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]

2016年1月14日 · Potassium nitrate is an inorganic salt with a chemical formula of KNO3. It is a natural source of nitrate and has been used as a constituent for several different purposes, including food preservatives, fertilizers, tree stump removal, rocket propellants, and fireworks.

Potassium nitrate (KNO3), an ionic white crystalline salt made up of potassium ions and nitrate ions. Uses of potassium nitrate include the manufacture of fertilizers, pesticides, glass, fireworks, explosives, and rocket fuels. It is also used as a food preservative, and when added to meat it

Potassium nitrate is an inorganic salt which has a molecular KNO3 formula. This is a common form of nitrate which has been used for numerous uses as a component, including agricultural preservatives, fertilisers, tree stump removal, rocket propellants, and fireworks.

2024年10月8日 · In the case of potassium nitrate (KNO3), the Lewis structure shows potassium at the center bonded to one nitrogen atom and three oxygen atoms. KNO3 has a planar molecular geometry, where the potassium-oxygen bonds are polar due to the difference in electronegativity between potassium and oxygen.

2017年9月24日 · The usual Lewis structure depicts a quaternized nitrogen (i.e. a nitrogen with a formal positive charge), a doubly bound N = O bond, and 2 × N −O− singly covalent bond....

2020年7月18日 · KNO3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.89–2.97 Å. N5+ is bonded in a trigonal planar geometry to three O2- atoms. All N–O bond lengths are 1.27 Å.

2024年7月11日 · Structurally, the potassium ion (K⁺) and the nitrate ion (NO₃⁻) are bonded together through ionic bonds. This means that the potassium atom gives up one electron to achieve a stable electronic arrangement, and this electron is gained by the nitrate group, creating a stable ionic structure.
