Overview

In our daily life, we come across many substances. Some of them are pure, while most are mixtures. A pure substance is made up of only one kind of particle, like an element or a compound. But mixtures contain two or more substances mixed together without any chemical change. These mixtures can be se

Key Concepts

Pure substances are either elements (like

Pure substances are either elements (like gold) or compounds (like sugar). They have fixed properties and a uniform composition. Mixtures are combinat

Homogeneous mixtures have uniform composition throughout

Homogeneous mixtures have uniform composition throughout, like salt dissolved in water. Heterogeneous mixtures have visible different parts, like sand

Different methods are used to separate

Different methods are used to separate mixtures based on physical properties. For example, hand-picking removes stones from rice, filtration separates

Separation depends on differences in properties

Separation depends on differences in properties like size, density, solubility, magnetic nature, or boiling point. For example, magnetic separation us
