The reaction of nitric acid and strontium carbonate to form strontium nitrate
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.[3][4]
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.[5]
Biochemistry
As a divalent ion with an ionic radius similar to that of Ca2+ (1.13 Å and 0.99 Å respectively), Sr2+ 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.[citation needed]
