Partition Equilibrium Calculator – A Level Chemistry

A free interactive chemistry calculator for practising partition equilibrium and solvent extraction calculations at A Level.

Students can explore calculations involving:

partition coefficients
equilibrium concentrations in two immiscible solvents
the amount of solute extracted
percentage extraction
single solvent extractions
multiple successive extractions
comparison of different extraction strategies

The calculator is designed as a teaching and checking tool, not simply an answer generator. Each stage is displayed clearly so students can follow the equilibrium reasoning and understand why several smaller extractions can be more effective than one large extraction.

The accompanying QR code gives direct access to the online calculator, making it useful for lessons, homework, revision and independent study.

Free to use – no login required.

Suitable for A Level and International A Level Chemistry.

Part of the free FranklyChemistry / ACE Chemistry interactive chemistry tools collection.
