Key Concepts

Density

Density is a physical property defined as mass per unit volume. It is used to characterize the compactness of a substance and is independent of its chemical composition, which means it remains the same regardless of whether the material is part of a solution or not.

Solubility

Solubility refers to the ability of a substance, the solute, to dissolve in another substance, the solvent, forming a homogeneous solution. It is a property that depends on the interactions between the solute and solvent molecules and varies with temperature and pressure.

Element

An element is a basic substance that consists entirely of one type of atom and cannot be broken down into simpler substances by chemical means. Each element is distinguished by its unique atomic number.

Compound

A compound is a substance formed when two or more different elements chemically combine in fixed proportions. The properties of a compound are typically different from those of the constituent elements, and compounds can only be separated into elements through chemical reactions.

Homogeneous Mixture

A homogeneous mixture, such as a solution, is one in which the components are uniformly distributed at the molecular level. This uniform composition means that the properties are consistent throughout the mixture.

Heterogeneous Mixture

A heterogeneous mixture contains visibly different substances or phases. The components in such a mixture are not uniformly distributed, which results in distinct regions or layers that can often be separated by physical means.
