Their chief characteristic is solubility in an alkaline solution, from which sulphuretted hydrogen produces a white precipitate of zinc sulphide.
The precipitate contains the zinc, which can be dissolved out by boiling with dilute sulphuric acid, and detected by the formation of a white precipitate on the addition of potassic ferrocyanide.
A white precipitate of sulphur will be formed, this will not interfere with the subsequent titration provided it is precipitated in the cold.
Diluted it gives with nitrate of silver, a white precipitate, which is insoluble in nitric acid and in caustic potash, but is soluble in ammonia, and when dried and heated melts, and forms a horny mass.
Sulphate of lime in excess gives a white precipitate, soluble in nitric or hydrochloric acid, but insoluble in oxalic, tartaric, acetic, or any vegetable acid.
Or if dissolved in nitric acid and a drop or two of HCl added, a white precipitate of AgCl will be formed, which may be collected and reduced with carbonate of soda upon charcoal.
Previous to the addition of the nitrate, the liquor should be well heated; otherwise, a white precipitate of dipyrophosphate of silver will be produced.
The solution of it in water must give a white precipitate with a solution of lead, and when neutralized with hydrochloric acid, and evaporated to dryness, it must not give an insoluble residue by dissolving it again in water.
It may be obtained artificially as a white precipitate, which rapidly turns blue or green on exposure, by mixing solutions of ferrous sulphate and sodium phosphate.
H2O, occurs as the mineral strengite, and is obtained as a yellowish-white precipitate by mixing solutions of ferric chloride and sodium phosphate.
H2O, is obtained as a white precipitate by mixing solutions of ferric chloride and ordinary sodium phosphate.
It reddens litmus freely and transiently, dissolves red oxide of mercury freely, forms a white precipitate of argentic cyanide when treated with silver nitrate, and responds to the other tests described hereafter.
Caesium and rubidium salts, even in dilute solutions, are precipitated by it; neutral solutions of ammonium chloride give with it a white precipitate, soluble with difficulty in large quantities of water.
Add to a portion of the suspected liquid a few drops of nitric acid, and then a solution of nitrate of barium; a white precipitate (sulphate of barium) will fall if sulphuric acid be present.
This precipitate is soluble in strong hydrochloric acid, which being diluted, throws down a white precipitate.
Caustic soda and potassa give a white precipitate (hydrated oxide) in solutions containing cadmium, insoluble in excess of the precipitant.
Sulphuric acid is added to the nitric solution as long as a white precipitate falls; after a time the precipitate is collected on a filter, washed with a mixture of water and alcohol, and ignited in a porcelain crucible.
It feebly reddens litmus paper, extinguishes the flame of a burning taper, and forms a white precipitate in aqueous solutions of lime and baryta, which is soluble in acetic acid.
Nitrate of baryta is then added to a portion of the fluid: in presence of sulphuric acid, a white precipitate, insoluble in acids, is produced.
Upon adding acetate of lead to the solution, a white precipitateis produced if phosphoric acid be present.
If lead ore be dissolved in nitric acid, the solution diluted, and some hydrochloric acid added, a white precipitate is thrown down.
If the ore is one containing bismuth, you should have a white precipitate; if it contains cobalt, you will get a bluish-green coloration.
The result is a white precipitateof the oxalate of lime, showing there is lime present, but not as a phosphate.
Note the formation of a white precipitate, which turns yellow.
Dilute the solution; add an excess of ammonia, and we find a white precipitate of the phosphate of lime and of magnesia.
By adding chloride of barium solution the sulphuric acid is bound to the barytes and sulphate of baryta separates as white precipitate.
To the filtrate is then added a solution of oxalate of ammonia until a white precipitate of oxalate of lime is formed.
In the solution effected with water containing some aqua ammonia of the brown substance, a white precipitate of oxalate of lime occurred when an oxalate of ammonia solution was added, but the brown substance remained in solution.
Sulphuric acid gives a white precipitate of calcium sulphate with strong solutions; ammonium oxalate gives calcium oxalate, practically insoluble in water and dilute acetic acid, but readily soluble in nitric or hydrochloric acid.
Cadmium hydroxide, Cd(OH)2, is obtained as a white precipitate by adding potassium hydroxide to a solution of any soluble cadmium salt.
Normal cadmium carbonates are unknown, a white precipitate of variable composition being obtained on the addition of solutions of the alkaline carbonates to soluble cadmium salts.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "white precipitate" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
