If you are studying chemistry and need to write assignments, essays, etc., then these pages can help!

Hands working in a chemistry lab

Chemistry is the study of the properties and structure of matter and how these change when different forces or substances are applied to them. Along with physics and the biological sciences, with which it shares a great deal, chemistry is one of the three fundamental physical sciences. All three also share ample opportunities for participating in cutting-edge research.

To write assignments about chemistry, the first thing you need to know is the vocabulary. We've analysed high-scoring student assignments to find the words that are used most often. For exercises about vocabulary related to chemistry go to this page:

Secondly, and most importantly, you will need to learn how to write certain types of assignments ('genres'). In chemistry, you will probably write Methodology Recounts, where you practise recording experimental findings by describing your methodology.  

This genre has an individual style you will need to learn. If you're short of time, you can go directly to the pages about Methodology Recounts, but we recommend you start at the beginning of 'Writing for a Purpose' and work through all of it. 

If you read all the materials, you'll be better able to identify what sort of assignment you have to write – your tutor usually won't tell you. Also, not all chemistry courses are the same and they might include assignments that aren't Methodology Recounts.


A selective method was developed for the residue analysis of paraquat and diquat residue analysis in various fruits including grape, apple, and pomegranate, etc. by using UPLC-MS/MS. The homegenised sample (10±0.1g) was extracted with acidified water (0.1M HCl), followed by heating in a water bath at 80°C for 15 min. The chromatographic separation was performed on hydrophilic interaction chromatography (HILIC).
