Kipp''s apparatus - Wikipedia
Kipp''s apparatus, also called Kipp generator, is an apparatus designed for preparation of small volumes of gases. It was invented around 1844 by the Dutch pharmacist Petrus Jacobus Kipp and widely used in chemical laboratories and for demonstrations in schools into the second half of the 20th century. It later fell out of use, at least in

Gravimetric analysis - Wikipedia
Precipitation method The precipitation method is the one used for the determination of the amount of calcium in water. Using this method, an excess of oxalic acid, H 2 C 2 O 4, is added to a measured, known volume of water.By adding a reagent, here ammonium oxalate, the calcium will precipitate as calcium oxalate.
