Meldrums Säure ist so sauer wie Essigsäure ist aber gar keine Carbonsäure sondern Malonsäureisopropylidenester.

Page 780 - Now the most startling result of Faraday's law is perhaps this. If we accept the hypothesis that the elementary substances are composed of atoms, we cannot avoid concluding that electricity also, positive as well as negative, is divided into definite elementary portions, which behave like atoms of electricity.
Page 780 - The same definite quantity of either positive or negative electricity moves always with each univalent ion, or with every unit of affinity of a multivalent ion.
Page 780 - Electrons are atoms of the chemical element, electricity; they possess mass ; they form compounds with other elements ; they are known in the free state, that is, as molecules ; they serve as the ' bonds of union
Page 779 - ... begin to perceive that chemical reactions, even those that occur with explosive violence, are far from being the sudden events they seem to ordinary human apprehension. What is really occurring in nature is a protracted and eventful struggle between the members of two opposing armies, each individual of which has his own personal history during the struggle, and is fully occupied with his own acts, which are, perhaps, as many, as various, and as different from those of his neighbours as are the...
Page 780 - ... two imponderable substances, because we shall have to speak principally on relations of quantity. We shall try to imitate Faraday as well as we can by keeping carefully within the domain of phenomena, and, therefore, need not speculate about the real nature of that which we call a quantity of positive or negative electricity.
Page 456 - The expenses of this research have been in part defrayed by a grant from the Government Grant Committee of the Royal Society, for which we desire to express our indebtedness.
Page 776 - A theory is a supposition which we hope to be true, a hypothesis is a supposition which we expect to be useful ; fictions belong to the realm of art ; if made to intrude elsewhere, they become either makebelieves or mistakes.
Page 275 - ... to this add about half its bulk of a warm saturated solution of cupric hydroxide in strong ammonia. Nitrogen is freely evolved during the addition, and the cupric is reduced to cuprous hydroxide, which remains dissolved in the ammoniacal liquid and does not undergo any immediate fuither reduction.
