In the hydrated state, Niobous acid. This oxide may be prepared in several ways :
— 1. By decomposing niobous chloride, NbCl3, with water : 2NbCl- + 3HX) = Nb-
O- + 6HCL. 2. By fusing colnmbite or other minerals containing it with acid ...

To separate niobaie of niobous acid from niobous acid, the process is exactly the
same, only that instead of muriatic acid of spec grav. 1-160, one of 1-094 is
employed. In this way niobate of niobous acid (Nb* 03, NbO*) is dissolved, and ...

Qualitative chemical analysis
potash, niobous anhydride fuses to a clear mass, soluble in water. With soda,
niobous anhydride fuses to a turbid mass, from which water dissolves the excess
of soda; after the removal of the latter, the niobite of sodium dissolves in water.

Niobium forms two oxides, whose composition has not been determined,
Niobous and Niobie Anhydrides. Rose has lately determined that these two
oxides contain the same metal : formerly he regarded the latter as the oxide of
another metal, ...
