Abstract

Two [97] compounds the one derived from the other by substitution are not necessarily analogues; they are not necessarily endowed with the same chemical function. Potassium chloride, a neutral salt, is derived from hydrochloric acid by substitution of potassium for hydrogen. Nitrogen chloride, which is not basic at all, is derived from ammonia by substitution of hydrogen by chlorine. Dumas proposed that the expression chemical type be used to denote the characteristic, distinct from analogy and chemical function, which relates two substances derived the one from the other by substitution. All compounds derived, immediately or mediately, from one another by some route of substitution of one element by another belong to the same chemical type.
