Barium oxalate.dihydrate

Despite some crystallographic similarities with the acid salt (see below), the water molecules in barium oxalate dihydrate are accommodated differently in the lattice [140]. The extent of water loss from BaC204.2H20 varied with pQi20). The products were the anhydrous salt below 4 Torr, the hemihydrate between 4 and 100 Torr, and the monohydrate above 100 Torr. The rate of water evolution at 353 K exhibited Smith-Topley behaviour and the changes in rate occur at values of pQyD) (5 and 100 Torr) which are close to those characteristic of the stabihty range of the hemihydrate.

Preparation of Potassium Trioxalatoferrate(III). First prepare barium oxalate. To do this, add a solution of 2.5 g of barium chloride dihydrate in 6 ml of water to a solution of 1.5 g of sodium oxalate in 40 ml of water. Filter off the formed crystals on a Buchner funnel and wash them several times with cold water.
