Amphoteric Colloids

1. When we plot the values of osmotic pressure, swelling, and viscosity of gelatin solutions as ordinates over the pH as abscissae, practically identical curves are obtained for the effect of monobasic acids (HCl, HBr, HNO(3), and acetic acid) on these properties. 2. The curves obtained for the effect of H(2)SO(4) on gelatin are much lower than those obtained for the effect of monobasic acids, ...

Amphoteric Colloids. I. Cii_emical Influence of the Hydrogen Ion Concentration

I t is often stated (Pauli, H6ber, and others) that both ions of a neutral salt affect the physical properties of an amphoteric electrolyte (ampholyte) simultaneously and in the opposite sense; so that the total result is the algebraic sum of the opposite action of the oppositely charged ions of the neutral salt. 1 The writer has beelz able to show by experiments on gelatin and on pig's bladder...

Nificance of the Isoelectric Point for the Purifi- Cation of Amphoteric Colloids. by Jacques Loeb

"Aluminium hydroxide dissolves in acids. From its solution in hydrochloric acid, an aluminlum salt, aluminium chloride A1C13, 6H20, is obtained. I t also combines with strong bases, dissolving for instance in a solution of sodium hydroxide and forming an aluminate, NaA102 . . . . According to the best knowledge we have on the subject, the molecule of aluminium hydroxide has the following struct...

Amphoteric Behavior of Complex

The hypothesis that a mixture of two ampholytes behaves, within certain limits, as an individual (1) with characteristics distinct from either component can also be semiquantitatively tested by certain conductivity experiments. These are based on the observation that the addition of such a substance as gelatin markedly decreases the observed conductivity of a phosphate solution. The magnitude o...

Amphoteric Behavior of Complex Systems

The amphoteric behavior of a system of two amphoteric components is theoretically examined; and this is shown to correspond more nearly with certain of the physical and chemical behaviors of living tissues than does the concept of a simple ampholyte.
