One is the unscientific method adopted in many works of using the same bath practically for about a month together without complete renewal. During this time a large quantity of a muddy precipitate accumulates, rich in hydrated oxide of iron or basic iron salts of an insoluble kind. This mud amounts to no less than 25 per cent. of the weight of the copperas used.
Now the protoxide readily combines with oxygen in the presence of water, forming the hydrated peroxide: these conditions it finds in passing through the lungs; it derives oxygen from the air, and finds water in the blood itself. This would already explain one portion of the phenomena of respiration.
In an experiment conducted by the Pennsylvania Experiment Station, during a period of sixteen years, eight tons of hydrated lime destroyed organic matter equivalent to thirty-seven tons of farm manure, as compared with the use of equivalent applications of ground limestone; and, as an average of the sixteen years, every ton of caustic lime applied liberated seven dollars' worth of organic nitrogen, as compared with ground limestone.
Hitherto the purification of the gas has been brought about by mechanical means, but the gas now enters the "purifier," in which it undergoes a further cleansing, but this time by chemical means. The agent used is either lime or hydrated oxide of iron, and by their means the gas is robbed of its carbonic acid and the greater part of its sulphur compounds.
This does no credit to the public intelligence, but the hunger of soils for lime is so great that investment at a price wholly out of proportion to the price of farm-slaked lime has rarely failed to yield some profit. Degree of Purity. It is always a reasonable assumption that hydrated lime has been made from stone of a good degree of purity.
"The results of this chemical investigation show that the chief advantages of this system of putrefaction are: "First. The active agent, hydrated ferrous oxide, is prepared within the sewage itself as a flocculent precipitate. "Second. Hydrated ferrous oxide is a deodorizer. "Third.
A by-product in the removal of magnesium from a magnesian limestone is an excellent material for correction of soil acidity, on account of its physical condition. Its exposure to the air causes much of the hydrate to change to an air-slaked form, and its value per ton lies somewhere between that of very finely pulverized limestone and hydrated lime. Magnesium.
In cyanuric acid, hydrated cyanic acid, and cyamelide, we have three such isomeric compounds. Cyanuric acid is crystalline, soluble in water, and capable of forming salts with metallic oxides. Hydrated cyanic acid is a volatile and highly blistering fluid, which cannot be brought into contact with water without being instantaneously decomposed.
The value of the lime is so great that one can well afford to draw water and apply with a hose so that the quantity can be controlled with exactness. When fresh burned lime is perfectly slaked, each 56 pounds of pure lime becomes 74 pounds of hydrated lime, water furnishing the added weight. Hydrated Lime on the Market. A popular form of lime on the market is the hydrate.
You mentioned also that you had seen some one who had used hydrated lime, but it didn't seem to make much of a clover crop.
