The chief sources of commercial potash are muriate of potash, sulfate of potash, and wood ashes.
Experiment stations often recommend the diluting of both the copper sulfate solution and the lime mixture to one-half the required amount before pouring together.
Use five gallons of stock solution of copper sulfate for every fifty gallons of bordeaux required.
It is preferable to dilute the copper sulfate solution.
Bordeaux mixture of other strengths, as recommended, is made in the same way, except that the amounts of copper sulfate and lime are varied.
I am old enough to remember when we used to develop our plates in ferrous sulfate solution and you never saw nicer negatives than we got with it.
Each year there would be deposited three to five inches of salts with a thin layer of calcium sulfate or gypsum on top.
It contains a lot of extra alumina, but after roasting in a kiln the potassium sulfate can be leached out.
The Germans get 5000 tons of potassium cyanide and as much ammonium sulfate annually from the waste liquor of their beet sugar factories and if it pays them to save this it ought to pay us where potash is dearer.
Another mineral source of potash is alunite, which is a sort of natural alum, or double sulfate of potassium and aluminum, with about ten per cent.
However, ammoniumsulfate does not eliminate or reduce worms when the soil contains large amounts of chalk or other forms of calcium that counteract acidity.
Rodale correctly pointed out that golf course groundskeepers use repeated applications of ammonium sulfate to eliminate earthworms from putting greens.
Howard especially denigrated sulfate of ammonia and single superphosphate as earthworm poisons.
Sidenote: The uses of quinin] Sulfate of quinin is the most common form of this drug.
Hence, the presence of glycerol, or glycerides, in any substance may usually be detected by mixing the material with anhydrous acid potassium sulfateand heating the mixture in a test tube, when the characteristic odor of acrolein will appear.
It is thus possible to work with much larger quantities of material when ferrous sulfate is employed.
It is also important to mix the materials well before applying heat; the aniline sulfate should have dissolved almost completely and the ferrous sulfate should be distributed throughout the solution.
In order to obtain a pure white hydrazine sulfate as the first precipitate, it is necessary to cool the hydrazine solution thoroughly and filter it twice before the sulfuric acid is added.
The mother liquor obtained from the crystallized hydrazine sulfate contains a small amount of hydrazine.
After the copper salt has been filtered off, the solution is concentrated until the hydrazine sulfate crystallizes.
Serving all ports and coast stations from Hull to Berwick, also Carlisle, &c.
The atmosphere consisted of 95 percent nitrogen and 5 percent carbon dioxide (no oxygen) and was dried, using calcium sulfate as a desiccant.
Scion Storage In earlier papers I described the use of sodium sulfate crystals (Glauber's salt) for controlling the humidity in scion storage.
When sulfate of copper and lime are added in this proportion, the compound is Bordeaux mixture.
It is, however, practicable to have stock preparation of sulfate of copper and of lime ready for mixing when required.
If fifty pounds of sulfate are suspended in twenty-five gallons of water on an evening, each gallon of water will, when stirred the next morning, hold two pounds of sulfate.
This is important for if the lime is added to so strong a solution of sulfate of copper, a curdling process will follow.
Sulfate of copper can be dissolved in water and held in solution until needed.
As a general rule more "process" lime is required to neutralize the copper sulfate than good stone lime.
To accomplish this the sulfate should be suspended at the surface of the water in a bag.
Bilious people have too little sodium sulfate, the melancholics are lacking in potassium sulfate and phosphate; too little calcium phosphate in the phlegmatics.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "sulfate" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: acidify; alcohol; carbonate; chemical; ferment; hydrate; nitrate; oxidize; reduce; work
