Qualitative Analysis tells you what a sample contains
It doesn't tell you how much of each - that's Quantitive analysis
Quantitive Analysis tells you how much it contains
Used to work out the molecular formula. If you had a sample containing carbon and hydrogen you'd no it's a hydrocarbon but without quantitive, you won't know if it's methane, butane etc.
Chemical Analysis is carried out on samples
Difficult to test all of the material -test a small bit
If something goes wrong, you can go back for another sample and try again
Must represent the bulk of the material bein tested
Samples are analyised in solution
Solution - dissolving the sample in a solvent - aqueous and non-aqueous
An aqueous solution = solvent = water. Non aqueous = Not water, eg; ethanol
Standard Procedures mean everyone does thngs the same way
Instructions, safest effective ways, most accurate way.
