Mixtures and Solutions (Science Experiments)
Suspensions and Solutions: Can filtration and evaporation determine whether mixtures are suspensions or solutions?
Design Your Own Experiment
Most of the substances we see around us are , combinations of different elements or compounds. The components of some mixturesuch as sandy water, which consists of grains of sand suspended in wateran easily be separated or will naturally settle. Others, such as salty water, form more permanent mixtures. How can we separate different kinds of mixtures into their component parts?
Mixtures that settleeparate out naturallyre called suspensionsA temporary mixture of a solid in a gas or liquid from which the solid will eventually settle out.. Sandy water is a good example of a suspension. Stirring will mix the sand and the water, but over time, the denser sand will fall to the bottom of the container, and a clear layer of water will appear above it.
A mixture whose parts remain stable and remain mixed over time is called a . Solutions commonly consist of a solid soluteThe substance that is dissolved to make a solution and exists in the least amount in a...
