Journal of General Physiology, 1919 1. When we plot the values of osmotic pressure, swelling, and viscosity of gelatin solutions as ordinates over the pH as abscissæ, practically identical curves are obtained for the effect of monobasic acids (HCl, HBr, HNO3, and acetic acid) on these properties. 2. The curves obtained for the effect of H2SO4 on gelatin are much lower than

Ionic behavior assessment of surface-active compounds from corn steep liquor by exchange resins [PDF]
, 2016 Depending on their ionic nature, biosurfactants can be classified as nonionic, anionic, cationic, or amphoteric. The ionic behavior of biosurfactants is an important characteristic that dictates their use in industrial applications.

Electrochemical removal of amphoteric ions [PDF]
Proceedings of the National Academy of Sciences, 2021 Significance Water treatment is required for a sustainable potable water supply and can be leveraged to harvest valuable elements. Crucial to these processes is the removal of charge pH-dependent species from polluted water, such as boron, ammonia, and phosphate. These species can be challenging for conventional technologies. Currently, boron
