A homogeneous mixture has a uniform composition and cannot be viewed as separate components. It exhibits uniform appearance and properties throughout. Homogeneous mixtures consist of a single phase, whether solid, liquid, or gas. They have identical composition in all parts and appear uniform to the naked eye. Homogeneous mixtures cannot be filtered because the mixture is uniform with no way to separate components. Common examples of homogeneous mixtures include solutions, alloys, air, and other mixtures used in daily life like drinks, cleaners, and blood plasma.
