Strontium nitrate
Template:Cs1 config Template:Chembox
Strontium nitrate is an inorganic compound composed of the elements strontium, nitrogen and oxygen with the formula Template:Chem2. This colorless solid is used as a red colorant and oxidizer in pyrotechnics.
Preparation
Strontium nitrate is typically generated by the reaction of nitric acid with strontium carbonate.[1]
Uses
Like many other strontium salts, strontium nitrate is used to produce a rich red flame in fireworks and road flares. Its strength as an oxidizer, which eliminates the need for large amounts of an additional chlorine-containing oxidizer, makes extremely pure colors in the orange-red to red color range attainable with simple compositions.[2][3]
Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation significantly better than using glycolic acid alone.[4]
Biochemistry
As a divalent ion with an ionic radius similar to that of Template:Chem2 (1.13 Å and 0.99 Å respectively), Template:Chem2 ions mimic calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. It is thus used in electrophysiology experiments.Script error: No such module "Unsubst".
