About Separating Mixtures
GoConqr OriginalWhat this unit covers
The resources follow the usual toolkit for splitting mixtures. The mind map Chemistry - Separation Techniques starts with filtration, which separates an insoluble solid from a liquid, and moves on to crystallisation. The DISTILLATION mind map sets out simple and fractional distillation and explains how the part of a solution with the lowest boiling point comes off first. Chromatography has the biggest cluster, with maps, notes, flashcards and slides.
Where to start
Begin with an overview, then narrow down.
- Open Chemistry - Separation Techniques to see the main methods side by side.
- Move to the Separating mixtures flashcards, which cover sieving and evaporation, among others.
- Look at the Chromatography mind map for the stationary phase, the mobile phase, and how components adsorb and desorb.
- Use the notes on Rf values when you are ready to work with results.
Using quizzes and maps together
Read a mind map first, then test yourself. The KS3 Reversible and Irreversible Changes Quiz is a gentle way in for younger secondary students. The IGCSE quiz on purifying and separating solutions suits those preparing for IGCSE Chemistry. Wrong answers show you which map to reopen. Flashcards such as Filtration under reduced pressure help you rehearse the steps of a method until you can draw and describe it.
Going further
Some resources reach beyond the basics. The HPLC mind map looks at resolution, selectivity and column length, and a gas chromatography slide set goes into instrumentation. These are handy for A-level Chemistry students stretching themselves, and for teachers who want extra material. The listed resources also mention GCSE Chemistry, MCAT and KS3.
Where it fits
This unit sits in the Matter and Its Properties strand of Chemistry. Pair it with the resources on solutions, solutes and solvents, since many separations depend on what is dissolved in what.

Frequently asked questions
Which resource should I open first?
Start with the mind map Chemistry - Separation Techniques. It gives a quick tour of filtration, crystallisation and other methods. After that, pick the DISTILLATION or Chromatography mind map for the technique you need, and follow up with a quiz to check what stuck.
What do the chromatography resources cover?
They range from basics to advanced work. The main mind map explains the stationary and mobile phases and how components adsorb and desorb. Other items cover paper and thin layer chromatography, Rf values, gas chromatography, HPLC and capillary electrophoresis.
Are the resources free to use?
Yes. Every resource listed here is free to open, study and take, with no account needed. They were made by GoConqr users rather than by GoConqr itself, so styles and depth vary from one resource to the next.
Which levels and exams do these suit?
Most of the material is secondary level, so it suits school students revising for GCSE Chemistry, IGCSE Chemistry or A-level Chemistry, plus KS3 science. A smaller share goes deeper, and the resources also mention the MCAT. Teachers can use them as ready-made material.
Can I check my knowledge with quizzes?
Yes. There are more than 30 quizzes, including ones on solutions, fractionating columns, gas chromatography and separation techniques in general. Try one after reading a mind map, then revisit the topics where you slipped.
What if I can't find what I need?
Make it yourself. A free account lets you build your own quizzes, mind maps, flashcards and notes, and saves your quiz scores. You could base a set on a method from this page, such as crystallisation, and tailor it to your course.
