Chromatography solubility
WebTOPIC: Experimental techniques and chemical analysis. Sub Topic:12.3 Chromatography. Syllabus Objectives: CORE: Describe how paper chromatography is used to separate mixtures of soluble coloured substances, using a suitable solvent. Interpret simple chromatograms to identify: (a) unknown substances by comparison with known substances. WebChromatography works because different substances in a mixture have different degrees of solubility. Solubility refers to how much of a particular substance can dissolve in a …
