Influence of Hydrogen Ion Concentration on Yeast Development.

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...

Effect of Dyes on Yeast Fermentation as in Fluenced by Hydrogen-ion Concentration "

The effect of hydrogen-ion concentration on the toxicity of various organic and inorganic compounds has been studied by a number of investigators. In general the results have shown that the toxicity of anions is increased by increasing the hydrogen-ion concentration and that of cations is increased by decreasing the hydrogen-ion concentration, provided the reaction does not affect the solubilit...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Influence of Hydrogen Ion Concentration on the Growth of Higher Plants under Controlled Conditions.

The effects of hydrogen ion concentration on plant growth occupy a prominient position in discussions of the adaptability of plants to their nutrient eiivironmelit. In the last two decades, with the improvements of methods of measurinig pH and particularly with the widespread adoption of the (lass eleetrode, increasing attention has been given to the hydrogen ion coneenitrationi in soils as it ...
