Fig. 87. H NMR spectra of barium chlorate hydrate, Ba(C103)2-H20 (426) (a) High-field powder spectrum (b) high-field single crystal spectrum (c) zero-field powder spectrum. The central peak arises from spins in crystallite orientations which did not evolve in zero field. All H20 proton proton vectors are coparallel in the unit cell.

Barium chlorate is interesting because it exists as a hydrate when crystallized from a water solution. It has the formula Ba(C 10 3) 2 H 2 0. Water molecules are found in the crystalline lattice in a one-to-one ratio with barium ions. The molecular weight of the hydrate is 322.3 (Ba + 2 + H 2O), so the wa-... 

Barium Diuranate, BaUjO, is obtained by heating barium uranyl acetate, or by heating together the green oxide and barium chlorate. It is obtained in a hydrated condition when ammonia is added to mixed solutions of barium chloride and uranyl nitrate, or when excess of baryta water is added to uranyl nitrate solution. It is a deep yellow crystalline powder. 

These can be prepared by electrolytic oxidation of chlorates(V) or by neutralisation of the acid with metals. Many chlorates(VII) are very soluble in water and indeed barium and magnesium chlorates-(VII) form hydrates of such low vapour pressure that they can be used as desiccants. The chlorate(VII) ion shows the least tendency of any negative ion to behave as a ligand, i.e. to form complexes with cations, and hence solutions of chlorates (VII) are used when it is desired to avoid complex formation in solution.
