<p></p> <p><b>Ny sida</b></p><div>{{DISPLAYTITLE:pH-indikator}}<br /> [[Fil:PH indicator paper.jpg|miniatyr|180px|pH-mätning med indikatorpapper]]<br /> En &#039;&#039;&#039;[[pH]]-indikator&#039;&#039;&#039; visar om en lösning är sur, basisk eller neutral. Det är ofta en svag syra eller bas som ändrar sin färg när de binder upp [[vätejon]]er (H&lt;sup&gt;+&lt;/sup&gt;) eller [[hydroxidjon]]er (OH&lt;sup&gt;-&lt;/sup&gt;). Indikatorer används i [[titrering]] när man till exempel ska bestämma en [[lösning]]s [[buffertförmåga]].<br /> <br /> De flesta pH-indikatorerna utgörs av organiska molekyler som innehåller [[konjugerat system|konjugerade dubbelbindningar]]. När en protonering/deprotonering sker vid konjugationen förskjuts molekylens absorptionsvåglängder, vilket medför färgförändringen.<br /> <br /> == Exempel på indikatorer ==<br /> *[[Antocyanin]] (finns naturligt i blommor och växter)<br /> *[[Bromtymolblått]] (BTB) indikerar surt, neutralt eller basiskt-<br /> *[[Fenolftalein]] indikerar surt eller basiskt<br /> *[[Indigokarmin]]<br /> *[[Malakitgrönt]]<br /> *[[Lackmuspapper]] indikerar surt eller basiskt<br /> *[[Universell indikator]] indikerar ett grovt pH-värde<br /> *[[Neutralrött]]<br /> <br /> == Naturliga pH-indikatorer ==<br /> <br /> {| class=&quot;wikitable&quot;<br /> !Växt !!
