In the acidic range, iron solubility increases as the temperature decreases. It was found that the largest factor examined in this study, affecting iron solubility during atmospheric transport, was mineralogy, with clays having higher solubility, 0.7–2.3% (moderately acidic leaching medium; pH 4.3) and 6.2–13% (acidic leaching medium; pH 1.7), overall than iron oxide minerals, <0.01–0.13% (moderately acidic leaching medium; pH 4.3) and 0.67–1.6% (acidic leaching medium; … {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://boiteacolis.be/#organization","name":"GEORGE Pakketboxen en pakketbrievenbussen","url":"https://boiteacolis.be/","sameAs":[],"logo":{"@type":"ImageObject","@id":"https://boiteacolis.be/#logo","inLanguage":"nl","url":"https://boiteacolis.be/wp-content/uploads/2017/10/george_tag_zr.png","width":2048,"height":341,"caption":"GEORGE Pakketboxen en pakketbrievenbussen"},"image":{"@id":"https://boiteacolis.be/#logo"}},{"@type":"WebSite","@id":"https://boiteacolis.be/#website","url":"https://boiteacolis.be/","name":"Bo\u00eetes-\u00e0-colis et bo\u00eetes aux lettres pour colis","description":"","publisher":{"@id":"https://boiteacolis.be/#organization"},"potentialAction":[{"@type":"SearchAction","target":"https://boiteacolis.be/?s={search_term_string}","query-input":"required name=search_term_string"}],"inLanguage":"nl"},{"@type":"WebPage","@id":"https://boiteacolis.be/2020/11/30/byvf8z61/#webpage","url":"https://boiteacolis.be/2020/11/30/byvf8z61/","name":"iron solubility curve - Bo\u00eetes-\u00e0-colis et bo\u00eetes aux lettres pour colis","isPartOf":{"@id":"https://boiteacolis.be/#website"},"datePublished":"2020-11-30T15:24:47+00:00","dateModified":"2020-11-30T15:24:47+00:00","inLanguage":"nl","potentialAction":[{"@type":"ReadAction","target":["https://boiteacolis.be/2020/11/30/byvf8z61/"]}]},{"@type":"Article","@id":"https://boiteacolis.be/2020/11/30/byvf8z61/#article","isPartOf":{"@id":"https://boiteacolis.be/2020/11/30/byvf8z61/#webpage"},"author":{"@id":""},"headline":"iron solubility curve","datePublished":"2020-11-30T15:24:47+00:00","dateModified":"2020-11-30T15:24:47+00:00","mainEntityOfPage":{"@id":"https://boiteacolis.be/2020/11/30/byvf8z61/#webpage"},"commentCount":0,"publisher":{"@id":"https://boiteacolis.be/#organization"},"articleSection":"Pakketboxen","inLanguage":"nl","potentialAction":[{"@type":"CommentAction","name":"Comment","target":["https://boiteacolis.be/2020/11/30/byvf8z61/#respond"]}]}]} Iron carbonate has a water solubility of 60 mg/L, iron sulphide of 6 mg/L, and iron vitriol even of 295 g/L. color: ; border-bottom: 1px dashed #ddd; of iron salts, iron chelates, polynuclear iron(III) complexes and carbohydrates.

Solubility refers to the amount of a substance that can be dissolved in water and the lower pH level, the more soluble the iron will be. The total solubility of iron at pH levels from 4 to 9 is shown graphically by seven curves for Eh values from 0.10 to +0.50.
