Heterogeneous mixtures like sand in water can be separated using filtration, while a mixture of sugar and salt cannot be separated this way.
Heterogeneous mixtures like sand in water can be separated by filtration, where the solid particles are left behind on the filter paper while the liquid passes through. Sugar and sand can also be separated using this method as sugar dissolves in water, allowing for filtration to isolate the sand. In contrast, a mixture of sugar and salt would not be separated through dissolving in water and filtration because both substances are soluble.
