Crystallization

Last week in science we made crystals using borax to see how they would separate and form from two different substances.

Aim - what was the purpose of crystallization?

To use crystallization to separate borax from water.

Results - the results weren't what I had expected them to be. I had thought that maybe the crystals would have grown bigger but they were really small. The crystals that had formed on the pipe cleaner grew big and on the bottom but when they broke off they were small. 


Conclusion - We dissolve the borax in the water. We made a concentrated solution and using crystallization we separated the borax from the water.

Solute borax 

Solvent water 

Equipment - beaker, heat mat, tripod, spatula, Gauze mat, bunsen burner, borax, pipe cleaner

Methos - boil water in a beaker on a gauze mat and tripod over a bunsen burner. when boiled turn the gas off. Add spatula heaps of borax, waiting for it to dissolve until adding more. When the solution is saturated leave to cool with a pipe cleaner suspended in the beaker

Discussion - where do crystallization useful in the real world? why do crystals make interesting shapes?

To make salt and sugar. Jewelry included.

  1. Well done Bailey, you are a very consistent blogger for you science *experiments. You followed the experiment structure and I really liked how you thought about your results and compared them to what you expected. Next steps are to answer the discussion questions in more detail.
