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..

Passive :: Passive (a.) Designating certain morbid conditions, as hemorrhage or dropsy, characterized by relaxation of the vessels and tissues, with deficient vitality and lack of reaction in the affected tissues..

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.

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

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..

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

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

Reagent :: Reagent (n.) A substance capable of producing with another a reaction, especially when employed to detect the presence of other bodies; a test..

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

Reactionaries :: Reactionaries (pl. ) of Reactionar.

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.

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..

Preaction :: Preaction (n.) Previous action.

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

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..

Reflux :: Reflux (n.) A flowing back, as the return of a fluid; ebb; reaction; as, the flux and reflux of the tides..

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

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

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

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..
