Prescribed Texts

There are no set texts but suitable reading materials will be made available in class


There will be a number of closely targetted references to the content covered in class and laboratory woprk given out through the course

Other Resources

Weblinks & Blackboard

The following web link is a good primer for looking at dilutions, with a further look at laboratory safety

A weblink will also be set up through the Prepare Solutions shell in My RMIT Studies (Blackboard) for specific RMIT Library resources

for this course

The RMIT Study & Learning Centre

As many students in this course have typically returned to study after a considerable break and there are often a diverse

range of study backgrounds, the The RMIT Study & Learning Centre is highly recommended as a way of getting extra help

to succeed in this course. It is situated near the HUB, ground level, Building 14 and provides chemistry-related help as well as individual appointments and a drop-in centre. You can go there in person to check availability of individual help and/or carefully look at their web page (;ID=vaatmxwjav8k (unresolved) )

Get in early,  if you need assistance!
