Strontium nitrate significantly better than using glycolic acid alone. As a divalent ion with an ionic radius similar to that of Ca (1.13 vs. 0.99 A, respectively), Sr ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. It is thus used in electrophysiology experiments. In his short story "A Germ Destroyer", Rudyard Kipling refers to strontium nitrate as the main ingredient of the titular fumigant. Strontium nitrate Strontium nitrate is an inorganic compound made of the elements strontium and nitrogen with the formula Sr(NO). This colorless solid is used as a red colorant and oxidizer
Sodium nitrate Hobbyist gold refiners use sodium nitrate to make a hybrid aqua regia that dissolves gold and other metals. Sodium nitrate is also a food additive used as a preservative and color fixative in cured meats and poultry; it is listed under its INS number 251 or E number E251. It is approved for use in the EU, USA and Australia and New Zealand. Sodium nitrate should not be confused with sodium nitrite, which is also a common food additive and preservative used, for example, in deli meats. Less common applications include as an oxidizer in fireworks, replacing potassium nitrate commonly
