'closeness' of a measurement to the true value.
name for ethanoic acid.
trivial name for propanone.
where a dilute solution of acid is used to extract basic compounds
out of an organic solution using a separating funnel.
portion of solution, usually measured with a volumetric pipette.
that is determined in a quantitative procedure such as volumetric
- Bumping Granule
pieces of a ceramic material that are added to solutions to prevent
the solution 'bumping' (see also).
where water is used to extract ionic impurities out of an organic
solution using a separating funnel.
known as a filter pump, a device that produces a vacuum (reduced pressure)
usng a flow of tap water. This can be used in Buchner filtrations,
vacuum distillations or with rotary evaporators.
of two or more liquids that cannot be separated by simple distillation.
An application of this is the addition of a second solvent to a solution
to produce a lower boiling azeotrope of the two solvents which is
easier to remove by evaporation.
