science

Aim to separate a solute from a solvent in a solution.

In science we did a distillation experiment and we separated the coke from the water is worked when we boiled the coke and it separated water from the coke and filled up in a different boiling tube.

 Equipment - A solution of saltwater , conical flask , heatproof mat , a delivery tube and bung , Bunsen burner , tripod , gauze mat , retort stand , boss head and clamp , boiling tube. \
Method -
 1. set up equipment as shown in the diagram   
2. add approximately 50 ml of saltwater into your conical flask  
 3. light your Bunsen burner open the air whole and genitally push the Bunsen burner  under the tripod  
4. heat the solution most of the solvent has been evaporated . Turn off the Bunsen burner 

How does distillation separate two liquids.
To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected. Repeating the process on the collected liquid to improve the purity of the product is called double distillation.

What are the two processes happening during this reaction.
The process of reactive distillation involves using the reaction vessel as the still. In this process, the product is usually significantly lower-boiling than its reactants. As the product is formed from the reactants, it is vaporized and removed from the reaction mixture.

how does distilation used in real life.
But chemists also use simpler physical methods,distillation and filtration, to separate mixtures.Distillation can be used to purify water, make alcohols, or separate petroleum into various components that range from natural gas to gasoline to tar.

  1. Hi Keira, cool blog! I really like the information you found on how distillation can be used to separate petrol and tar. Next time I would love to hear your own words about what you found out.
