analytical procedures

know the difference between qualitative and quantitative

be familiar with how samples are analysed in the lab

chromatography

what is it?

aqueous and non aqueous solvents

how does it work (dynamic equilibrium)

how does it separate?

using a reference database of materials

compare paper and thin layer chromatography

gas chromatography

mobile phase

stationary phase

calculate RF value

locating agents

how it works

retention time

interpret results

titrations

steps by step procedure

concentration is grams per dm3

how to make a standard solution

degree of uncertainty in results

measure accurately sample volume

dissolving if needed

measuring colour change/ volume needed

work out concentration from titration results
