Strontium nitrate

<h2 id="preparation">Preparation</h2>
<p>Strontium nitrate is typically generated by the reaction of <a href="/facts/Nitric_acid/UDbwGp6s">nitric acid</a> on <a href="/facts/Strontium_carbonate/08rRdbXQ">strontium carbonate</a>.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>
</p>
2 HNO3 + SrCO3 → Sr(NO3)2 + <a href="/facts/Water/0lkXnJPK">H2O</a> + <a href="/facts/Carbon_dioxide/xGzpppEp">CO2</a>

<h2 id="uses">Uses</h2>
<p>Like many other strontium salts, strontium nitrate is used to produce a rich red flame in <a href="/facts/Firework/sPEQcu3h">fireworks</a> and <a href="/facts/Road_flare/LuXg6UXI">road flares</a>. The oxidizing properties of this salt are advantageous in such applications.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> 
</p><p>Strontium nitrate can aid in eliminating and lessening skin irritations. When mixed with <a href="/facts/Glycolic_acid/Y0urKYuy">glycolic acid</a>, strontium nitrate reduces the sensation of skin irritation significantly better than using glycolic acid alone.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
</p>
<h2 id="biochemistry">Biochemistry</h2>
<p>As a divalent ion with an ionic radius similar to that of Ca2+ (1.13 Å and 0.99 Å respectively), Sr2+ ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings. It is thus used in <a href="/facts/Electrophysiology/VPd5VYzm">electrophysiology</a> experiments.

<h2 id="in-popular-culture">In popular culture</h2>
<p>In his short story "<a href="/facts/A_Germ-Destroyer/jEgo0vEn">A Germ-Destroyer</a>", <a href="/facts/Rudyard_Kipling/jmHXpRzn">Rudyard Kipling</a> refers to strontium nitrate as the main ingredient of the titular <a href="/facts/Fumigant/QGCodNPb">fumigant</a>.
