6) concentration of hydrogen ion 氢离子浓度 例句>> 补充资料:氢离子浓度指数 分子式:CAS号:性质:又称PH值。PH是以氢离子浓度表示的水的酸、碱性的量度,氢离子浓度是每升溶液中氢离子的质量(以克表示),用氢指数PH来表示,故PH便是氢离子浓度指数。PH在数值上等于氢离子浓度的负对数,即氢离子浓度倒数的对数...
The small "p" stands for "the power of," and together the two letters are short for "the negative logarithm of thehydrogen-ionconcentration." Alternatively, the formula is written as follows: Do you really know what pH is? (Technical Briefs) ...
Formula for Hydrogen Ion Concentration:Finding the hydrogen ion concentration of a solution from the pH of the solution simply requires us to multiply 1 times 10 with a negative exponent of the pH number.Answer and Explanation: Become a Study.com member to unlock this answer! Crea...
At this time, molecular ions (SiH<->) comprising silicon and hydrogen are measured in addition to a single atom ion (H<->). Then, the hydrogen concentration (H) in the silicon nitride film is expressed by a formula A, where K1 and K2 are constants. These values can be obtained by ...
What is the pH of an aqueous solution with a hydrogen ion concentration of H = 1.4 * 10-8 M?pH Formula:To calculate pH based on the concentration of hydrogen ions, the following formula is used: {eq}pH = -\log{[H^+]} {/eq}...
and connections among them. As an important part of hydrogen network, a purification unit is placed to upgrade the hydrogen concentration of certain sources to reuse them. In order to reduce fresh hydrogen consumption, the values of purification streams, including feed, purified product, as well ...
(formally at infinite temperature),kis Boltzmann constant andEais the so-called activation energy for permeation. For the variety of glasses, the hydrogen permeabilityKcan be described by the empirical formula (Tsugawa et al., 1976) as a function of the absolute temperatureTand the concentration...
The pH, which means the power of Hydrogen, is the quantitative expression of the acidity and basicity of a chemical substance.it can be calculated by the concentration of hydrogen ions in the solution through the formula {eq}\rm{pH=-log[H^+]}{/eq}. The usual pH scale...
where, in the last two equations, the nitrogen and carbon activities in the substrate at its surface have been replaced by the corresponding concentration values (to be expressed in [mol/m3] in view of the values given for the rate coefficients inTable 1.5). ...
