Solutions are a type of mixture where one substance is evenly mixed into another. The substance that is mixed in is called the solute, and the substance it mixes with is the solvent. Solutions appear uniform throughout and do not show separate parts. Common examples include saltwater and sugar water.

Solutions are found in liquids, gases, and solids around the world. They are present in oceans, air, and many everyday products. Different types of solutions exist in nature and human-made materials.

Solutions are common in daily life and in natural systems. They are part of how substances are combined in a uniform way. Solutions can be found in many environments on Earth.
