Distillation Basics and Simple Distillation
Distillation is basically a clever way of purifying liquids using heat and cooling - think of it like a sophisticated evaporation process. You heat up a mixture, turn one part into gas, then cool it back down to get a pure liquid.
There are two main types: simple and fractional distillation. Simple distillation works brilliantly when you want to separate a liquid from a solution (like getting pure water from salty seawater).
Here's how simple distillation works: you heat the solution until the liquid with the lowest boiling point evaporates first. This gas travels through a condenser where it cools down and turns back into pure liquid that drips out for collection.
Quick Tip: Remember that the substance with the lowest boiling point always evaporates first - this is key to understanding why distillation works!
The setup includes a flask for heating, a thermometer to monitor temperature, and a condenser (the cooling bit) where cold water flows around the gas to turn it back into liquid. It's like a mini water cycle in your chemistry lab!
