Suspensions

Suspensions are unstable physical mixtures of undissolved particles in a liquid.

• Compared to Solutions, Suspension contain larger and fewer miscible particles.

• The particles are generally larger and visible to the naked eye but also not large enough to settle quickly to the bottom.

• They are unstable and they separate when left still, exactly like Water and Sand.

They are unstable and separate over time which is why some lotions and creams can separate in the bottle and may need to be shaken before they are used.

Examples: The glitter in nail polish (separate from the nail polish but stays together. Calamine lotion is another example.
