Option a. Coffee is an example of a homogeneous mixture.
What is a homogeneous mixture?
- A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture.
- The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample.
- Often it is easy to confuse a homogeneous mixture with a pure substance because they are both uniform.
- The difference is that the composition of the substance is always the same.
- The amount of salt in the salt water can vary from one sample to another.
- All solutions would be considered homogeneous because the dissolved material is present in the same amount throughout the solution.
- One characteristic of mixtures is that they can be separated into their components.
- Since each part of the mixture has not reacted with another part of the mixture, the identities of the different materials are unchanged.
