Methylene blue‚ having the largest molecular weight‚ displayed the smallest diameter 15.67 and diffused at the slowest rate (0.78mm/min). Next is potassium permanganate with a diameter of 13.33 mm and rate of diffusion of 2.54mm/min. The fastest is the potassium permanganate with 13.33 mm diameter and diffusion rate of 2

Chapter 1 The Chemical World Chemistry a science that studies matter – its properties and changes. Matter is anything that has mass and takes up space. Matter is made up of atoms and molecules. Scientific Method Observation of nature → Hypothesis (possible explanation) → Experiments to confirm or revise hypothesis Many observations lead to scientific law – a statement of the relationship between different parts of nature. Ex: law of conservation of mass- “ matter is neither created or destroyed”
