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..

Explosive :: Explosive (n.) An explosive agent; a compound or mixture susceptible of a rapid chemical reaction, as gunpowder, or nitro-glycerine..

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

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

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

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

Sequence :: Sequence (n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences..

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

Magnesia :: Magnesia (n.) A light earthy white substance, consisting of magnesium oxide, and obtained by heating magnesium hydrate or carbonate, or by burning magnesium. It has a slightly alkaline reaction, and is used in medicine as a mild antacid laxative. See Magnesium..

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..

Reactionary :: Reactionary (n.) One who favors reaction, or seeks to undo political progress or revolution..

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..

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..

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

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

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

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.

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..

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

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..
