In some cases, up to 90% of particles were removed thanks to the boiling and filtering process, although the effectiveness varied depending on the type of water.

The limewater test for carbon dioxide is also a qualitative analysis based on a precipitation reaction. Limewater is a solution of calcium hydroxide and the precipitate is calcium carbonate.
