Does it seem that dieticians and nutrition experts seem to make a huge fuss about eating foods that seem to contain infinitesimal amounts of those mysterious substances known as vitamins?
Well, there is some good, sound chemistry behind why this is so.
Find out about the chemistry of vitamins with AUS-e-TUTE's newest set of resources!

Gravimetric Analysis
Gravimetric analysis can be used to determine the quantity of an ion present in a solution.
This can be done by adding a reagent that causes the ion under investigation to form an insoluble compound (a precipitate) that precipitates out of the solution.
