Answer to Question #58433 in General Chemistry for Annalise Skinner

Question

Is filtration used to remove soluble substances from a liquid?
Is evaporation used to remove soluble substances from a liquid?
Do you lose the solvent when you separate a solution using evaporation?
Are you left with a solvent when you use separate a solution using evaporation?

Answer 1

Filtration can’t be used to remove soluble substances from the liquid. It removes only insoluble substances.
Evaporation (with a subsequent liquid condensation) can be used to remove soluble substances from the liquid.
The solvent is lost during evaporation, but it can be collected back by the condensation.
When we use to separate a solution using evaporation we are left with the “dry” solid.
