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

Monitor your My RMIT studies (Blackboard) site for this, Course Announcements & other Course-Related material


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!
