Evaporation experiment.

This week during science we have been learning about evaporation.Evaporation is when a liquid is turned into a gas.

Aim:The aim is to Evaporate copper sulfate(Blue Liquid) and to separate the liquid

Equipment:

-Glasses

-Copper sulfate solution

-250m Beaker

-Heat proof mat

-Evaporating basin

-Element

Method:Set up element,Add 100ml of hot water to the beaker and place on the element,the add copper sulfate to the evaporating basin until it is quarter full,Then carefully place the evaporating basin on top of the beaker,

next we turned the element up to 6 then we heated the solution until most of the solvent has been evaporated and crystals of solute are forming.Then finally turn off the element.

Distillation experiments

Introduction: Today we did an experiment on Distillation, Evaporation, and Condensation, and it was also a really good day...

Aim: To separate a solute from a solvent in a solution using distillation.

Equipment: Solution Of Coke, Conical Flask, Heat Proof Mat, Delivery tube, Bunsen burner, Tripod, Gauze Mat, Bosshead & Clamp, Boiling tube, Retort stand.

Method:
1. A mixture of coke and water was heated in a conical flask…
2. The water evaporates leaving the coke behind…
3. The water vapour flows through the delivery tube…
4. Heat the solution until most of the solvent has been evaporated. Turn off your element……………………..

Results: We saw that the coke started to bubble because of the heat of the element, then at the end of the experiment there was syrup at the bottom.

Discussion: In conclusion of what in the photos, some of the photos have just a layer of coke on the bottom it looks like that because the liquid was separated from to coke mixture by being boiled and heated.

The normal coke mixture had a thicker layer of sugar than the other one this is because the normal coke mixture that the coke zero mixture.

Distillation: The  coke started boiling because it was being heated by the element then the liquid turned  into gas and then it entered the delivery tube next the gas the gas turned into a solvent because it was sitting in a beaker full of ice and then the solute was left in to bottom of the flask
