Unit 3 - Researching Chemistry & Investigation Ideas

Experimental Techniques

This is very good for the details of how to do the various techniques:
Chemistry: A Practical Guide

Very good website from Royal Society of Chemistry:
Interactive Lab primer - links to lots of techniques
https://edu.rsc.org/resources/interactive-lab-primer/1064.article

Apparatus - https://edu.rsc.org/resources/the-interactive-lab-primer-lab-apparatus/2266.article

Aspirin Experiments
A lot about preparation of aspirin, use of re-crystallisation, melting point, and thin layer chromatography http://www.rsc.org/learn-chemistry/content/filerepository/CMP/00/000/045/Aspirin.pdf
Synthesis of Aspirin : https://www.youtube.com/watch?v=Y4NMpO1xI8U
Synthesis of Aspirin - very good video - shows crystallisation and vacuum filtration and explanations along the way from the teacher - https://www.youtube.com/watch?v=ojZ9hpi-9w0

Recrystallisation and Vacuum Filtration to purify a compound - from Thinkwell videos with Professor Yee - very good explanation
https://www.youtube.com/watch?v=RNTtTzR8lrg
and more about recrystallisation - ignore the actual experiment here but there is some nice info and  a nice diagram : http://www.users.miamioh.edu/gungbw/CHM244/pdfs/expt_3_2012.pdf

Separating Funnel
a lovely 1min 30 sec video to show this https://www.youtube.com/watch?v=uXtH7TsPRaQ

Weighing by Difference:
Analytical Balance
from Thinkwell - v good videos
https://www.youtube.com/watch?v=dNeNBx8nAyQ

Titrations
Worth watching to get finer points of doing these at Adv Higher Level
Colorimetry - using a smart meter on your mobile phone
