DISSENTERS

‘Nonconformists,’ has, those who di ent from the teaching of | the Church of England; call themselves | hypothesis first formulated by the lower| Swedish chemist Arrhenius, and now generally accepted as one of the basic theories of physical chemistry. It states of| thot when acids, bases, and salts are of di olved in water, they split up or into | -giscociate’ into fons. For instance, wt an when hydrochloric Z acid gas is di olved; A a bik acta it 1 Ee poaanbed | i200 4ydrogen ions bearing a positive now arin and chlorine ions ees Le Na scene panies stances Gonsidaralt ionize when di olved Fon @nstarice: in water | a canal|jonized to the extent of Aca i3 BS cent., while a solution of hydrochloric acid of equal strength is about 95 per War,| cent. fonized. The chemical behavior an of a substance depends to a very large degree on the extent to which it di ociates in solution, and during recent years methods have been evolved of} so, determining the concentration of hydrogen ions in a solution. Such law,| determinations frequently have far of|¢ greater significance than the mere re capac- | ity of the solution for neutralizing an of alkali. See CumMistTRy.
