Revulsion :: Revulsion (n.) A sudden reaction; a sudden and complete change; -- applied to the feelings.

Reflex :: Reflex (a.) Produced in reaction, in resistance, or in return..

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

Reciprocity :: Reciprocity (n.) Mutual action and reaction.

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..

Reactionist :: Reactionist (n.) A reactionary.

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

Pearlash :: Pearlash (n.) A white amorphous or granular substance which consists principally of potassium carbonate, and has a strong alkaline reaction. It is obtained by lixiviating wood ashes, and evaporating the lye, and has been an important source of potassium compounds. It is used in making soap, glass, etc..

Earth :: Earth (n.) A similar oxide, having a slight alkaline reaction, as lime, magnesia, strontia, baryta..

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..

Wheel :: Wheel (n.) A firework which, while burning, is caused to revolve on an axis by the reaction of the escaping gases..

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

Xanthoproteic :: Xanthoproteic (a.) Pertaining to, or derived from, xanthoprotein; showing the characters of xanthoprotein; as, xanthoproteic acid; the xanthoproteic reaction for albumin..

Diazotize :: Diazotize (v. t.) To subject to such reactions or processes that diazo compounds, or their derivatives, shall be produced by chemical exchange or substitution..

Reactionaries :: Reactionaries (pl. ) of Reactionar.

Electro-muscular :: Electro-muscular (a.) Pertaining the reaction (contraction) of the muscles under electricity, or their sensibility to it..

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..

Catalysis :: Catalysis (n.) A process by which reaction occurs in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyali

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.
