Why does potassium manganate spread in water without even stirring it?

When you drop a purple crystal into water, its particles break away and randomly move between the water particles. They travel from an area of high concentration to low concentration until they are evenly spread. This process is called Diffusion!

It's a foundational chemistry topic you must master for your IGCSE Chemistry 0620 (exams 2026, 2027, 2028), O Level, and A Level science papers.

Watch the video and drop your answer to the quick quiz at the end! Is it A or B? 👇

Do you know the difference between Rest & Motion, Volume & Density, and Resistance & Conductivity?
Many students mix these up in exams! Our latest video simplifies these concepts for IGCSE, GCSE, O Level, and A Level learners preparing for Cambridge & Edexcel exams.
