Bromoform :: Bromoform (n.) A colorless liquid, CHBr3, having an agreeable odor and sweetish taste. It is produced by the simultaneous action of bromine and caustic potash upon wood spirit, alcohol, or acetone, as also by certain other reactions. In composition it is the same as chloroform, with the substitution of bromine for chlorine. It is somewhat similar to chloroform in its effects..

Reactive :: Reactive (a.) Having power to react; tending to reaction; of the nature of reaction.

Reaction :: Reaction (n.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame..

Abutment :: Abutment (n.) A fixed point or surface from which resistance or reaction is obtained, as the cylinder head of a steam engine, the fulcrum of a lever, etc..

Saleratus :: Saleratus (n.) Aerated salt; a white crystalline substance having an alkaline taste and reaction, consisting of sodium bicarbonate (see under Sodium.) It is largely used in cooking, with sour milk (lactic acid) or cream of tartar as a substitute for yeast. It is also an ingredient of most baking powders, and is used in the preparation of effervescing drinks..

Water Wheel :: Water wheel () Any wheel for propelling machinery or for other purposes, that is made to rotate by the direct action of water; -- called an overshot wheel when the water is applied at the top, an undershot wheel when at the bottom, a breast wheel when at an intermediate point; other forms are called reaction wheel, vortex wheel, turbine wheel, etc..

Reaction :: Reaction (n.) Backward tendency or movement after revolution, reform, or great progress in any direction..

Synthesis :: Synthesis (n.) The art or process of making a compound by putting the ingredients together, as contrasted with analysis; thus, water is made by synthesis from hydrogen and oxygen; hence, specifically, the building up of complex compounds by special reactions, whereby their component radicals are so grouped that the resulting substances are identical in every respect with the natural articles when such occur; thus, artificial alcohol, urea, indigo blue, alizarin, etc., are made by synthesis..

Acidimetry :: Acidimetry (n.) The measurement of the strength of acids, especially by a chemical process based on the law of chemical combinations, or the fact that, to produce a complete reaction, a certain definite weight of reagent is required..

Reaction :: Reaction (n.) Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.

Antiperistasis :: Antiperistasis (n.) Opposition by which the quality opposed asquires strength; resistance or reaction roused by opposition or by the action of an opposite principle or quality.

Preaction :: Preaction (n.) Previous action.

Resist :: Resist (v. t.) To counteract, as a force, by inertia or reaction..

Reaction :: Reaction (n.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.

Lactamide :: Lactamide (n.) An acid amide derived from lactic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine..

Coagulate :: Coagulate (v. t.) To cause (a liquid) to change into a curdlike or semisolid state, not by evaporation but by some kind of chemical reaction; to curdle; as, rennet coagulates milk; heat coagulates the white of an egg..

Bile :: Bile (n.) A yellow, or greenish, viscid fluid, usually alkaline in reaction, secreted by the liver. It passes into the intestines, where it aids in the digestive process. Its characteristic constituents are the bile salts, and coloring matters..

Barker''s Mill :: Barker's mill () A machine, invented in the 17th century, worked by a form of reaction wheel. The water flows into a vertical tube and gushes from apertures in hollow horizontal arms, causing the machine to revolve on its axis..

Basic :: Basic (a.) Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper..

Incompatible :: Incompatible (a.) Incapable of being together without mutual reaction or decomposition, as certain medicines..
