Chromatography & Distillation Explained | GCSE Chemistry Core Practical 1 (Separating Inks)

Is your pen lying to you?In this episode of GCSE Science Simplified, we break down GCSE Chemistry Core Practical 1 — investigating the composition of inks using paper chromatography and simple distillation.You’ll learn how scientists separate mixtures and reveal what substances are really present, using clear explanations, memorable models, and exam-ready language.We cover:How paper chromatography works (mobile phase vs stationary phase)How to interpret a chromatogramHow to identify pure and impure substancesHow to compare unknown substances using Rf valuesWhy key method steps matter (pencil lines, solvent level, solvent front)The principles behind simple distillation and separation by boiling pointPerfect for:GCSE Chemistry revision (Edexcel, AQA, OCR)Understanding core practical experimentsImproving exam technique and avoiding common mistakesThis episode helps you move beyond memorising steps — and actually understand how and why separation techniques work.Listen now to master chromatography, distillation, and core practical skills for GCSE success.
