Buffers are the first line of defense in maintaining a constant hydrogen-ion concentration in body fluids, and a brief description of the mode of action of buffers is necessary. An acid is a substance that has the potential to dissociate and release hydrogen ions, and so become acidic. If ...
Hydrogen cyanide, a highly volatile, colorless, and extremely poisonous liquid. A solution of hydrogen cyanide in water is called hydrocyanic acid, or prussic acid. It was discovered in 1782 by a Swedish chemist, Carl Wilhelm Scheele, who prepared it fro

(Chemistry) potential of hydrogen; a measure of the acidity or alkalinity of a solution equal to the common logarithm of the reciprocal of the concentration of hydrogen ions in moles per cubic decimetre of solution. Pure water has a pH of 7, acid solutions have a pH less than 7, and alk...
Hydrogen has the potential to be a major energy vector in a renewable and sustainable future energy mix. The efficient production, storage and delivery of hydrogen are key technical issues that require improvement before its potential can be realized. In
The cell is operated at 60 °C in 1 mol L−1 sulphuric acid and experimentally characterized by polarization curves and electrochemical impedance spectroscopy (EIS). At 2.0 V cell potential a current density of ≈450mAcm−2 was reached corresponding to an iridium mass specific current density...
In this work, BESS uses lithium batteries and lead-acid batteries as energy storage batteries, and its daily self-discharge rate is low (0.1~0.3%). Therefore, this work only considers the power exchange between BESS and ADN. The charge–discharge model of BESS is as follows: {𝐸𝐵(𝑡...
(Fig.2c). In this study, we tested several hygroscopic materials, including CH3COOK, KOH, and H2SO4, representing a salt, a base, and an acid, respectively. All three materials spontaneously absorb moisture from the air and form ionic electrolytes. It was found that the direct air ...
Note that both electrolytes are poorly dissociated at supercritical temperatures and hence are classified as being a weak acid and a weak base, respectively. Furthermore, the corresponding, fully dissociated salts, which would be required for an effective buffer to be formulated, do not exist. ...
