Suspensions are mixtures where insoluble particles are suspended in a liquid or gas. They are created by combining an insoluble solid with a solvent, such as mixing sand and water to form a sand-water suspension. Suspensions are non-homogeneous, leave behind undissolved residue when filtered, and separate over time as the insoluble particles sink, making them unable to transmit light completely. Common examples include milo drink, coffee with milk, and salad dressing.

What are Suspensions? Suspensions are mixtures in which insoluble particles are suspended in a liquid or gas.
How do we create a Suspension? Insoluble solid + Solvent = Solution Example: sand + water sand water (insoluble solid) (solvent) suspension The liquid which is used to dissolve the solid Residue after filtering
Properties of Suspensions Non-homogeneous all particles in the mixture are not evenly distributed Leaves behind residue (undissolved solid) after filtering the suspension
Properties of Suspensions Solute and solvent separate when left to stand Solute particles mostly sink to the bottom of the container Light is unable to pass through completely.
Examples of Suspensions Milo drink Coffee/tea with milk Salad dressing
