Salt water is classified as a homogeneous mixture. Here’s a brief explanation of each option you provided and why salt water fits the classification of a homogeneous mixture:
-
Homogeneous mixture: Salt water is a uniform solution where the salt (solute) is completely dissolved in water (solvent), making it look like a single phase.
-
Heterogeneous mixture: This is not true for salt water, as you cannot distinguish different components with the naked eye.
-
Pure substance: Salt water is not a pure substance because it contains more than one substance (salt and water).
-
Can be separated: While this is technically true (the salt can be separated from the water through processes like evaporation), it is more accurate to say that salt water is a homogeneous mixture, categorizing it based on its uniformity.
So, the best answer is that salt water is a homogeneous mixture.
