How to interpret a flame test
Flame tests are a very easy way to distinguish between ionic metal salts. Learning how to interpret their results is an important skill for chemistry students. When energy is applied (in this case from the flame) electrons in the metal
How to predict your degree classification
Want to predict your final degree classification? OK – so its just a bit of fun! But (now graduated) MChem student, Euan Diodge, has devised an awesome spreadsheet that can be used to “predict” your final degree classification based on
How to give a good presentation
Where presentations are concerned, students seem to be divided into two distinct groups. There are the few that seem completely at home when talking to groups, and then there are the majority for whom presenting anything to a group is

How to calculate a solution concentration
Calculating solution concentration is something undergraduates can find confusing and frustrating. We’ve all been there when asked to make a solution of some compound to a specific concentration. We usually begin by collecting numbers from random places, then try fitting
