ency of a specific fungus or ferment (Mycoderma aceti). The process involves two distinct reactions, in which the oxygen of the air is essential. An intermediate product, aldehyde, is formed in the first process. 1. C2H6O + O = H2O + C2H4O

ach attended with fever. -- Gastric juice (Physiol.), a thin, watery fluid, with an acid reaction, secreted by a peculiar set of glands contained in the mucous membrane of the stomach. It consists mainly of dilute hydrochloric acid and the ferment pepsin. It is the most important digestive fluid in the body, but acts…

ectromotive force to the current. It is equal to R2 + X2, where R = ohmic resistance, X = reactance. For an inductive circuit, X = 2pfL, where f = frequency and L = self-inductance; for a circuit with capacity X = 1 ÷ 2pfC, where C = capacity.

Incapable of being together without mutual reaction or decomposition, as certain medicines. Incompatible terms (Logic), terms which can not be combined in thought.

derived from lactic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine.

a sirupy, colorless fluid, soluble in water, with an intensely sour taste and strong acid reaction. There are at least three isomeric modifications all having the formula C3H6O3. Sarcolactic or paralactic acid occurs chiefly in dead muscle tissue, while ordinary lactic acid results from fermentation. The two acids are…

A white, crystalline substance, having a bitter taste and a neutral reaction, and forming one of the essential ingredients of lactucarium.

he impressed force, and takes place in the direction in which the force is impressed. (3) Reaction is always equal and opposite to action, that is to say, the actions of two bodies upon each other are always equal and in opposite directions. -- Marine law, or Maritime law, the law of the sea; a branch of the law merch…

ar 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.

and phenol. Its solution in alkalies is brilliant red, but is decolorized by acids. This reaction, being very delicate, is used as an indicator.

enol. Its solution in alkalies is brilliant red, but is decolorized by acids, and as this reaction is exceedingly delicate it is used as an indicator.

In a strict sense the term post-impressionism is used to denote the effort at self-expression, rather than representation, shown i…

ioned by affinity and composition; thus, combustion, explosion, and certain solutions are reactions occasioned by chemical properties. Chemical properties are identical when there is identity of composition and structure, and change according as the composition changes. 3. Organoleptic properties, or those forming a cl…
