What makes a mixture a solution? Looking at Solutions What makes a mixture a solution?

What is a solution? A solution is a mixture of two or more substances. So, what make a solution a special type of mixture? A solution is homogenous- that means all the particles are evenly mixed throughout the solution.

What is a solution? A solution can exist in any state: Solid Liquid Brass is a solid solution. Brass is an alloy (a homogenous mixture) of copper and zinc. Liquid Sugar water is a liquid solution. Sugar water is a homogenous mixture of sugar and water. Gas Air is a gaseous solution. Air is a homogenous solution of nitrogen, oxygen, and carbon dioxide.

Comparing a Mixture and Solution + + sand water sugar water The sugar is dissolved in the water. The sugar particles are evenly distributed in the water. You can separate the sand from the water by filtering.
