The tin deoxidizes the molybdic acid to a certain degree, and converts it into the molybdous, which when evaporated and heated with alumina recently precipitated, forms this blue pigment.
A blue may also be obtained by putting intomolybdic acid, (made by digesting sulphuret of molybdenum with nitric acid,) some filings of tin, and a little muriatic acid.
Molybdic acid is one of the more expensive reagents.
A large excess of the magnesium solution tends both to throw out magnesium hydroxide (shown by a persistently flocculent precipitate) and to cause the phosphate to carry down molybdic acid.
The tendency of the magnesium precipitate to carry down molybdic acid is also increased if the solution is too concentrated.
Observations upon Molybdic Acid, and its Combinations with Acidifiable Bases[43].
On this account molybdic acid is often used in the estimation of the phosphoric acid present in a substance.
By exposing molybdic acid, mixed with charcoal and placed in a covered crucible, to the strongest heat of a smith's forge.
It is brittle and very infusible; when heated in contact with the air, it is converted into molybdic anhydride, MoO{3}.
The excess of silver can be separated by hydric chloride, and the phosphoric acid made evident by the addition of molybdic acid in excess.
A very similar method is practised by Sonnenschein and others with the aid of phospho-molybdic acid.
In the filtrate from phospho-molybdate, ptomaines may also be found by treating with lead acetate to get rid of the phospho-molybdic acid, and then adding certain reactives.
The phospho-molybdic acid precipitate is decomposed with neutral lead acetate, which process may be facilitated by heating on the water-bath.
If the molybdic acid is fairly reduced by this means, it is to be moistened by nitric acid, and the heating repeated.
The hydrochloride gives precipitates in aqueous solution with phospho-molybdic acid, phospho-antimonic acid, and potassium bismuth iodide; the latter is in the form of red plates.
The molybdicsolution must be mixed in excess with the liquid under treatment, the temperature raised to 70 deg.
The alcoholic extract is evaporated, dissolved in a little water, neutralised with soda, acidulated with nitric acid, and precipitated with phospho-molybdic acid.
The hydrochloride is a deliquescent syrup, not forming any compound with gold chloride, but uniting with phospho-molybdic acid in forming a compound crystallising in cubes.
Metallic molybdenum, its protoxide and binoxide, are converted in the oxidation flame into molybdic acid.
At a higher temperature, it is oxidized to molybdic acid, when it glimmers and smokes, and is converted into crystallized molybdic acid upon the surface.
Upon charcoal the soda and the molybdic acid are absorbed, the latter is reduced to the metallic state, the metal remaining as a grey powder after washing off the particles of charcoal.
Molybdenum (Mo) occurs in the metallic state; also combined with sulphur, or as molybdic acid combined with lead.
If intumescence takes place, the presence of either tartaric acid, molybdic acid, silicic, or tungstic acid, is indicated.
He examined the characters of this acid, called molybdic acid, and the nature of the salts which it is capable of forming by uniting with bases.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "molybdic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
