Ferric ammonium sulphate, also called ammonium iron(III) sulfate or ferric alum, is a soluble iron salt used in analytical chemistry, notably as the indicator in Volhard titrations of silver and halides with thiocyanate and as an oxidising titrant in redox titrations such as the determination of titanium. This 0.1N solution provides precise, standardized iron content for accurate volumetric analysis and redox reactions. Catalogue details: CAS 7783-83-7, molecular formula (NH₄)Fe(SO₄)₂, molecular weight 266.01 g/mol. Store at ambient conditions. Signal word: Warning (may cause skin irritation). Molekula supplies Ferric Ammonium Sulphate, 0.1N solution from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
