Alkaline carbonates give precipitates of basic carbonates, the formation of which is also retarded by the presence of ammonium salts.
This is basic economics.
When confronted with any thorny societal problem, I apply the same basic thought process I used on the five topics of this book.

For rails of basic open-hearth steel, which is rapidly ousting Bessemer steel, the Civil Engineers' specifications allowed from o 65 to 0-75% of carbon with 0-05% of phosphorus, while the specifications of the American Railway Engineering and Maintenance of Way Association provided for a range of 0.75 to 0-85% of carbon, with a maximum of 0.03% of phosphorus.
They include gypsum, dolomite, conglomerates, phyllites, and a basic series of eruptive rocks (gabbros, peridotites, serpentines).
Histones are a class of albumins soluble in water and acids, but essentially basic in character; hence they are precipitated by alkalies.
The thiazoles are somewhat basic in character, and combine with the alkyl iodides to form thiazolium iodides.
It is certain, however, that most obsidians are very acid or rhyolitic. The dark, semiopaque glassy forms of the basic igneous rocks are known as tachylytes.
To the extent of 4 to 6%, and rather less in the other species, is expelled only at a high temperature; it is therefore water of constitution, existing as basic hydrogen or as hydroxyl replacing fluorine.
Of other lead minerals we may mention the basic sulphate lanarkite, PbO PbSO 4; leadhillite, PbSO 4.3PbCO 3; the basic chlorides matlockite, PbO PbC12j and mendipite, PbC1 2.2PbO; the chloro-phosphate pyromorphite, PbC12.3Pb3(P04)2, the chloro-arsenate mimetesite, PbC12.3Pb3(As04)2; the molybdate wulfenite, PbMoO 4; the chromate crocoite or crocoisite, PbCrO 4; the tungstate stolzite, PbW04.
We must also excuse Hippocrates for his belief that the human body is composed of four basic substances called "humors" that must be kept in balance.
While agriculture itself is a technology, it is, in its most basic form, extremely low tech.
As we contemplate whether we absolutely must end war, we should consider how life lived on a war footing affects our most basic rights and freedoms.
Twitter already has saved lives, toppled dictatorships, and silenced its numerous critics whose basic argument was "because I don't understand this, it must be irrelevant."
Dusty wasn't sure how Pierre ever made it through the Guardian basic training with his lip.
6), melts at 180-181°C. The simple oxypyrimidines are obtained by the action of nitrous acid on the amino derivatives, or by heating these latter with concentrated hydrochloric acid to 180° C. They show both basic and phenolic properties and are indifferent to the action of reducing agents.
PHARMACOSIDERITE, a mineral species consisting of hydrated basic ferric arsenate, 2FeAs04 Fe(OH)3.5H20.
It is a basic oxide, dissolving readily in acids, with the formation of salts, somewhat analogous to those of zinc.
The oxides of type RO are soluble in water, the solution possessing a strongly alkaline reaction and rapidly absorbing carbon dioxide on exposure; they are basic in character and dissolve readily in acids with the formation of the corresponding salts.
In its vivid blue colour it contrasts strikingly with the emerald-green malachite, also a basic copper carbonate, but containing rather more water and less carbon dioxide.
In America, the basic units have been the ton-mile and the passenger-mile, and these figures are now required to be furnished to the Interstate Commerce Commission and to most of the state commissions as well.
Besides the plant beds extensive outflows of basic lava rest directly upon the Cambrian and Ordovician strata.
In the northern unfolded region great flows of basic lava lie directly upon the Cambrian and Ordovician beds of Siberia, but are certainly in part of Tertiary age.
A year or two later field trials were begun in England, with the final result that basic slag has become recognized as a valuable source of phosphorus for growing crops, and is now in constant demand for application to the soil as a fertilizer.
These are modified forms of basic rocks such as basalt, dolerite and diabase.
Under extreme crushing these basic rocks may be converted into dark biotite-schists, or greenish chloriteschists.
They are silicates, usually orthosilicates, of aluminium together with alkalis (potassium, sodium, lithium, rarely rubidium and caesium), basic hydrogen, and, in some species magnesium, ferrous and ferric iron, rarely chromium, manganese and barium.
Haemoglobin is composed of a basic albumin and an acid substance haematin; it combines readily with oxygen, carbon dioxide and carbon monoxide to form loose compounds.
It was found advantageous not to work for acid but for a basic calcium nitrate (normal calcium nitrate being very deliquescent); for this purpose the acid is treated with the requisite amount of milk of lime.
They are either colourless liquids, which boil without decomposition, or crystalline solids; and are both basic and acidic in character.
Pectolite is a secondary mineral occurring as white masses with a radially fibrous structure in the veins and cavities of basic igneous rocks.
It is a feebly basic, colourless liquid which boils at 130° C., and possesses a smell resembling that of chloroform.
Zinc dust and hydrochloric acid reduce pyrrol to pyrrolin (dihydropyrrol), C 4 H 6 NH, a liquid which boils at 90° C. (748 mm.); it is soluble in water and has strongly basic properties and an alkaline reaction.
Sodium phenolate is heated in a stream of carbon dioxide in an iron retort at a temperature of 180-220° C., when half the phenol distils over and a basic sodium salicylate is left.
When boiled with calcium chloride and ammonia, salicylic acid gives a precipitate of insoluble basic calcium salicylate, C 6 H 4 ‹ 0 2 i Ca, a reaction which serves to distinguish it from the isomeric metaand para-hydroxybenzoic acids.
The chromophoric groups are rarely strongly acid or basic; on the other hand, the auxochromes are strongly acid or basic and form salts very readily.
With basic substances, the chromophoric combination with a colourless acid is generally attended by a deepening in colour; auxochromic combination, on the other hand, with a lessening.
