Columbium can be determined volumetrically making use of stoichiometric factor. The causes of low results which have been obtained by several investigators seem to be, (1) failure to bring columbium oxide into reducible form, (2) unstability of its solution being easily subjected to hydrolysis, and (3) slowness with which it is reduced. Bearing these points in mind, the authors have found a method with satisfactory result. By the method as little as 1mg of columbium oxide and as well as 2mg of is in 50mg of tantalum oxide can be determined.
