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.
Hazardous Decomposition Products : Oxides of nitrogen and toxic metal fumes may form when heated to decomposition. Hazardous Polymerization: Will not occur. Incompatibilities: Heavy metals, phosphites, organic compounds, carbonaceous materials, strong acids, and many other substances.
The rate of reaction increases with temperature, but the extent of reaction decreases. At 550 °C and 600 °C the reaction is continuous and eventually goes to completion. From 650 °C to 750 °C, as the case of decomposition of potassium nitrate is, the system attains equilibrium. At 790 °C, a rapid decrease in volume is first observed ...
Sodium nitrate is the chemical compound with the formula Na N O 3.This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate.
The decomposition of potassium chlorate was also used to provide the oxygen supply for limelights. Potassium chlorate is used also as a pesticide. In Finland it was sold under trade name Fegabit. Potassium chlorate can react with sulfuric acid to form a highly reactive solution of chloric acid and potassium sulfate: 2 KClO 3 + H 2 SO 4 → 2 ...
This composition, usually in a ratio of 5 parts potassium nitrate, to 3 parts aluminum powder, to 2 parts sulfur, is especially popular with hobbyists.
Many different sugars are used as the fuel for rocket candy. The most common fuel is typically sucrose, however, glucose and fructose are sometimes used. As an alternative, sorbitol, a sugar alcohol commonly used as a sweetener in food, produces a propellant with a slower burn rate and is less brittle when made into propellant grains. [5]
Niter or nitre [5] is the mineral form of potassium nitrate, KNO 3.It is a soft, white, highly soluble mineral found primarily in arid climates or cave deposits. Historically, the term niter was not well differentiated from natron, both of which have been very vaguely defined but generally refer to compounds of sodium or potassium joined with carbonate or nitrate ions.
