Solutions are groups of molecules that are mixed and evenly distributed. Scientists say that solutions are homogenous systems. Everything in a solution is evenly spread out and thoroughly mixed.

Solution

Solution Let's compare sugar in water (H 2 O) to sand in water. Sugar dissolves and is spread throughout the glass of water. The sand sinks to the bottom. The sugar-water is a homogenous mixture while the sandwater is a heterogeneous mixture. Both are mixtures, but only the sugar-water can also be called a solution.

Miscible Liquids that can mix without separating.
