A homogeneous mixture is a combination of two or more substances that are evenly distributed throughout. In this type of mixture, the individual components cannot be easily distinguished from one another. Common examples include saltwater and air, where the different substances blend uniformly, creating a consistent composition. In a homogeneous mixture, the properties remain the same throughout the mixture. This means that if you take a sample from any part of the mixture, it will have the same composition as any other sample. This characteristic distinguishes homogeneous mixtures from heterogeneous mixtures, where the components are not uniformly distributed.
