What is a solution in which the composition and properties are uniform throughout called?

A homogeneous mixture, such as a solution, has particles of the solute dispersed evenly throughout the solvent. This uniformizes the mixture, leaving only one visible phase.

Examples of Homogeneous Mixtures (Solutions):

  1. Saltwater: A solution of salt (solute) in water (solvent).
  2. Air: A mixture of nitrogen (solvent) with oxygen and other gases (solutes).
  3. Sugar in Water: A solution where sugar dissolves uniformly in water.
