Introduction
Solutions are homogeneous mixtures usually classified based on their physical state, including solid solutions, gaseous solutions, and liquid solutions.
Solid Solutions: Composed of at least one substance, which is the solvent, mixed with a specific quantity of another substance, identified as the solute.
Gaseous Solutions: Homogeneous mixtures of gases that do not react with each other.
Liquid Solutions: One of the components is a liquid before being mixed with another substance. The liquid component is called the solvent, and the process is known as dissolution.
The solute can be a liquid, solid, or gas.
