## Why is matter pure?

True Solution is a homogeneous mixture of two or more substances in which substance dissolved (solute) in solvent has the particle size of less than 10-9 m or 1 nm. Simple solution of sugar in water is an example of true solution.

## What is a mixture Class 9?

When a scientist says that something is pure, it means that all the constituent particles of that substance are the same in their chemical nature. A pure substance consists of a single type of particles. In other words, a substance is a pure single form of matter.

## Is water a pure?

If two or more substances (elements or compounds) are mixed together in any proportion, and they do not undergo any chemical change but retain their properties, the resulting substance is called mixture.
