Il blu intenso è causato dal <a href="/wiki/Trasferimento_di_elettroni" title="Trasferimento di elettroni">trasferimento di elettroni</a> da un atomo di <a href="/wiki/Ferro" title="Ferro">ferro</a> a un altro all'interno della <a href="/wiki/Molecola" title="Molecola">molecola</a>. Viene assorbita luce a 680 nm (<a href="/wiki/Rosso" title="Rosso">rosso</a>), provocando il trasferimento di un elettrone da un atomo di Fe(II) a uno vicino di Fe(III). La luce trasmessa risulta blu. </p><p>Nonostante la presenza dello <a href="/wiki/Ione" title="Ione">ione</a> di <a href="/wiki/Cianuro" title="Cianuro">cianuro</a>, il blu di Prussia, come altri ferrocianuri, non è particolarmente tossico a causa del forte legame tra gli ioni di cianuro e di ferro. Comunque, se trattato con <a href="/wiki/Acido" title="Acido">acidi</a> forti concentrati, può liberare il cianuro in forma di cianuro di idrogeno, più noto come <a href="/wiki/Acido_cianidrico" title="Acido cianidrico">acido cianidrico</a>, che è estremamente tossico. </p> <div class="mw-heading mw-heading2"><h2 id="Impieghi">Impieghi</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Blu_di_Prussia&veaction=edit&section=2" title="Modifica la sezione Impieghi" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Blu_di_Prussia&action=edit&section=2" title="Edit section's source code: Impieghi"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Il blu di Prussia è un colore intenso e tende verso il nero o il viola scuro quando viene mischiato con altri <a href="/wiki/Colori_a_olio" class="mw-redirect" title="Colori a olio">colori a olio</a>. </p><p>Sospeso come <a href="/wiki/Colloide" title="Colloide">colloide</a> in acqua, il blu di Prussia è la base della <a href="/wiki/Tintura" title="Tintura">tintura</a> in blu dei <a href="/wiki/Tessuto_(materiale)" title="Tessuto (materiale)">tessuti</a>. Venne impiegato come colore nelle uniformi degli eserciti prussiani e degli eserciti francesi napoleonici; in particolare i francesi lo chiamarono <i>bleu national</i>. </p><p>Il blu di Prussia può essere utilizzato anche da agente <a href="/wiki/Chelazione" title="Chelazione">chelante</a> e nel trattamento per l'<a href="/wiki/Avvelenamento" title="Avvelenamento">avvelenamento</a> da metalli pesanti.

Quindi può essere usato per indicare la regolarità di una superficie o di un supporto. </p><p><a href="/wiki/Joseph_Whitworth" title="Joseph Whitworth">Joseph Whitworth</a> rese popolare il primo metodo pratico per preparare accuratamente delle superfici piatte negli <a href="/wiki/Anni_1830" title="Anni 1830">anni 1830</a>, usando il blu di Prussia e delle tecniche di raschiamento su tre superfici di prova. Fino alla sua introduzione delle tecniche di raschiamento, lo stesso metodo con tre superfici veniva usato con delle tecniche di lucidatura che davano però risultati meno accurati. Ciò portò a un'esplosione dello sviluppo di strumenti di precisione che usavano queste tecniche per generare superfici piatte come base per l'ulteriore costruzione di forme precise. </p><p>Il blu di Prussia può essere miscelato con alcoli metilati per creare una macchia ad essiccazione rapida. Queste macchie vengono usate per le operazioni di marcatura nella lavorazione dei metalli, per trasferire lo schema di lavorazione sul pezzo prima che venga lavorato. </p> <div class="mw-heading mw-heading2"><h2 id="Voci_correlate">Voci correlate</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Blu_di_Prussia&veaction=edit&section=3" title="Modifica la sezione Voci correlate" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Blu_di_Prussia&action=edit&section=3" title="Edit section's source code: Voci correlate"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Ferrocianuro_di_potassio" title="Ferrocianuro di potassio">Ferrocianuro di potassio</a></li> <li><a href="/wiki/Ferricianuro_di_potassio" title="Ferricianuro di potassio">Ferricianuro di potassio</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Altri_progetti">Altri progetti</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Blu_di_Prussia&veaction=edit&section=4" title="Modifica la sezione Altri progetti" class="mw-editsection-visualeditor"><span>modifica</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Blu_di_Prussia&action=edit&section=4" title="Edit section's source code: Altri progetti"><span>modifica wikitesto</span></a><span class="mw-editsection-bracket">]</span></span></div> <div id="interProject" class="toccolours" style="display: none;
