Usage examples of manganese.
Magnesium, aluminium, iron, zinc, nickel, cobalt, manganese, and cadmium dissolve, with evolution of hydrogen, in the cold acid, or when warmed.
In the absence of manganese and cobalt the titration may be made without further separation.
It may be removed by passing sulphuretted hydrogen through the filtrate from the acetate separation: sulphides of nickel, cobalt and zinc will be precipitated, whilst manganese remains in solution: the addition of more sodium acetate may assist the precipitation.
The solution will contain the zinc, together with any manganese the ore contained, and, perhaps, traces of nickel and cobalt.
The oxide of manganese will be precipitated, and can be ignited and weighed.
To the hydrochloric acid solution of the zinc and manganese add sodium acetate in large excess and pass sulphuretted hydrogen freely.
The precipitate, freed from manganese, is then dissolved in hydrochloric acid and titrated.
Generally a small, but decided, precipitate of alumina comes down, together with sulphides of any zinc or manganese which is present.
If the percentage of dioxide is required it may be calculated by multiplying the percentage of manganese by 1.
It must be borne in mind that the manganese should never be calculated to dioxide except when it is known to exist in the ore only in that form.
The depth of colour depends on the amount of manganese present, and this should not much exceed 10 milligrams.
A quantity of substance containing not more than this amount of manganese should be boiled for a few minutes with 25 c.
The manganese is determined in the titrated solution by precipitation as dioxide and titrating.
If the dishes show a manganese stain, wash them out with a few drops of hydrochloric and sulphurous acids.
