Simple Distillation Flashcards
What type of seperation technique is distillation ?
Physical separation technique
What do we use simple distillation for ?
Separating a dissolved solid from a liquid but keep the liquid
What are the two stages of distillation ?
Evaporate the liquid by heating causing it to vaporize
Condense the vapor back into a liquid by cooling
What is the apparatus used to carry out simple distillation ?
Place solution into a flask which is don red to a continuous glass tube
This is surrounded by a condenser which keeps the internal glass tube cold
There is also a thermometer
How do we carry out simple distillation ?
Set up apparatus: bunsen burner, condenser, continues glass tube and thermometer
First heat the solution until it boils using bunsen burner, the liquid evaporates into a vapor which rises up the glass tube then into the condenser which condenses the vapor turning it back into a liquid which is then collected in a beaker
At the end of distillation what are we left with ?
Solid crystals and the liquid
What do we use distillation for ?
To produce drinking water from sea water however a lot of energy is used
