Is salt water a homogeneous or heterogeneous mixture?
Understand the Problem
The question is asking whether salt water should be classified as a homogeneous or heterogeneous mixture. This requires an understanding of the definitions and characteristics of mixtures in physical chemistry.
Answer
homogeneous mixture
Saltwater is a homogeneous mixture.
Answer for screen readers
Saltwater is a homogeneous mixture.
More Information
Homogeneous mixtures have uniform composition throughout, meaning you cannot see or distinguish the different components. In saltwater, salt dissolves completely and uniformly in water, making the mixture appear as one substance.
Tips
A common mistake is thinking that saltwater is heterogeneous if salt crystals are not fully dissolved. Ensure the salt is fully dissolved to correctly identify the mixture.
