Gravity Filtration and Vacuum Filtration

9th - Higher Ed
The first laboratory technique that we will learn together is a very simple one, filtration. This is how we separate a mixture of liquids and solids. There are two common ways a chemist will perform filtration, those being gravity...

Recrystallization and Melting Point Analysis

9th - Higher Ed
Now that we have covered some important separation techniques, let's take a look at a purification technique. Sometimes a chemical reaction will produce a solid, which can precipitate from solution. But these crystals typically contain...
