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, ...
متن کاملAmphoteric 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...
متن کاملAmphoteric 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.
متن کاملAmphoteric Polymers to Improve Paper
The objective of the present work is to evaluate the application of an amphoteric polymer, with acidic and basic groups on the polymer chain, as a paper dry strength additive. The polymer studied here is random terpolymer of high electrostatic charge density, and high molecular weight. The results of our work showed that the balance between the charge densities of the surface and the polymer st...
متن کاملThe Accumulation of Electrolytes Vii. Organic Electrolytes
I t has been suggested that potassium may enter Valonia chiefly as KOH which reacts with an organic acid HA in the sap to form KA, after which A is exchanged for chloride so that potassium accumulates as'KC1. This is not contradicted by any known facts and it is supported by a variety of evidence; inasmuch as this has recently been discussed I it need not be cited here. Other cations may act si...
