Corrosive substance Corrosive substance A corrosive substance is one that will damage or destroy other substances with which it comes into contact by means of a chemical reaction. The word "corrosive" is derived from the Latin verb "corrodere", which means "to gnaw", indicating how these substances seem to "gnaw" their way through flesh or other materials. The word corrosive refers to any chemical that will dissolve the structure of an object. They can be acids, oxidizers, or bases. When they come in contact with a surface, the surface deteriorates. The deterioration can happen in minutes, e.g. concentrated muriatic acid spilled on skin;
Chemical substance in several molar mass distributions, LDPE, MDPE, HDPE and UHMWPE. The concept of a "chemical substance" became firmly established in the late eighteenth century after work by the chemist Joseph Proust on the composition of some pure chemical compounds such as basic copper carbonate. He deduced that, "All samples of a compound have the same composition; that is, all samples have the same proportions, by mass, of the elements present in the compound." This is now known as the law of constant composition. Later with the advancement of methods for chemical synthesis particularly in the realm of organic chemistry; the
