What is a homogeneous mixture?

Back

A mixture that has a uniform composition throughout, where the individual components are not distinguishable, such as saltwater.

Front

What is the difference between a solution and a colloid?

Back

A solution has particles that are completely dissolved and cannot be seen, while a colloid has larger particles that remain suspended.
