These two methods yield selenic acid combined with an alkali, and it is difficult
and tedious to separate and combine it with certain other bases. In his first
experiments with chlorine gas upon the metallic sele- niurets of the Hartz, the
solution ...
sulphuric acid, selenic acid, and peroxide of manganese, are distilled together,
the selenium does not unite with an additional dose of oxygen, but oxygen gas is
disengaged, and there are formed a sulphate and a seleniate of manganese.

The biseleniate is obtained when the preceding salt is dissolved in selenic acid.
The solution crystallizes to the last drop in the form of small prisms, which are not
altered by exposure to the air. Caustic ammonia removes one half of the acid, ...

When. procured by the process above described, selenic acid always contains
water, but it is very difficult to ascertain its precise proportion. Some acid which
had been heated higher than 576°, contained, subtracting the quantity of
selenious ...

Selenic acid is prepared by fusing selenium, selenious acid, a selegite or a
metallic selenuret with nitre. Selenuret of lead, being the most abundant source,
has been used for this purpose, but being accompanied by sulphuret, the selenic
acid ...

To separate the selenic acid, the solution is to be decomposed by nitrate of lead;
the seleniate of lead is as insoluble as the sulphate, and being well washed, is to
be decomposed by a current of sulphuretted hydrogen, which has no action on ...

The seleniate of lead, which is as insoluble as the sulphate, after being well
washed, is treated by a current of sulphuretted hydrogen gas, which does not
decompose selenic acid. The excess of sulphuretted hydrogen is driven oil' by
heat, and ...

When this is boiled on it, proto-seleniate of mercury is formed, and the nitric acid
contains selenic acid. If muriatic acid be poured on the seleniate, selenium is
precipitated ; the oxygen of the selenic acid passing to the mercury, by which the
red ...
