Is Matter Around Us Pure topics:
Have you ever noticed the tag word pure written on the packs of these consumables? For an ordinary person, pure means having no adulteration. For a scientist, all these things are mixtures of different substances and hence not pure. For example, milk is a colloidal solution of water, fat, proteins etc. So, when a chemist says a substance is pure, it means that, in their molecular essence, all the constituent particles are the same. A single form of particle has a pure material. A material is, in other words, a pure single type of matter.
