Welcome to AS Practical Skills Assessment

This page provides resources to cover the Practical Skills Assessment (PSA) (for CHM3T - Centre Assessed Route) and the Practical Skills Verification (PSV) (for CHM3X - Externally Assessed Route)
Candidates must attempt at least two tasks from PSA1, PSA2 and PSA3 (AS Inorganic Chemistry), at least two tasks from PSA4, PSA5 and PSA6 (AS Physical Chemistry) and at least two tasks from PSA7, PSA8 and PSA9 (AS Organic Chemistry)

Term 1
PSA1 - Make up a volumetric solution
PSA2 - Carry out a simple acid-base titration
Class Practical 1 (PSA2) (worked answer)
Class Practical 2 (PSA1, PSA2) (worked answer)
Class Practical 3 (PSA1, PSA2) (worked answer)
PSA5 - Determine the Mr of a volatile liquid or the Mr of a gas

Term 2
PSA4 - Measure an enthalpy change
Class Practical 4 (PSA4) (worked answer)
Class Practical 5 (PSA4) (worked answer)
PSA6 - Investigate how the rate of a reaction varies with temperature
Class Practical 6 (PSA6) (worked answer)
PSA3 - Carry out some inorganic tests
PSA9 - Investigate the combustion of alcohols
Class Practical 7 (PSA9) (worked answer)
PSA8 - Carry out some organic tests
Class Practical 8 (PSA8) (worked answer)
PSA7 - Distil a Product from a Reaction
PSA7A - Distil a Product from a Reaction
