I need some help for the A2 Chemistry Practical (Edexcel). I'm not sure what to write when writing observations. Is it OK to write "No precipitate" ? Do I have to write complete sentances?
No, writing 'no ppte formed' is perfectly acceptable. You could also state the colour of the solution. Go on to www.edexcel.org.uk and download the unit 6 specimin paper and mark scheme. It shows you how observations should be written.
