Is salt water homogeneous or heterogeneous?
Salt water is made by mixing salt (NaCl) in water. It is a homogeneous mixture and a heterogeneous one. A difference between the two is that concentration is same everywhere in case of a homogeneous mixture, whereas, in case of a heterogeneous mixture, the concentration varies from place to place within a mixture. An easy test to check the homogeneous or heterogeneous nature of salt water is by tasting salt water taken from different points within the sample. A similar example of a homogeneous mixture is sugar water, that is, water containing sugar. An example of a heterogeneous mixture is trail mix, where we can mix various components in any fraction and after mixing find heterogeneity in component distribution. Same is the case with fruit salad.,Hope this helps.
