氢离子浓度指数(hydrogen ion concentration),一般称为“pH”,由丹麦生物化学家Soren Peter Lauritz Sorensen在1909年提出。符号p来自德语Potenz,意思是“浓度”;H代表氢离子(hydrogen ion)。 发布于 2023-06-13 14:30・IP 属地安徽 写下你的评论... ...
n (pH) The concentration of hydrogen ions in solution when the concentration is expressed as gram-ionic weights per liter. A convenient form of expressing hydrogen ion concentration is in terms of the negative logarithm of this concentration. The negative logarithm of the hydrogen ion concentration...
The meaning of HYDROGEN-ION CONCENTRATION is the concentration of hydrogen ions in a solution expressed usually in moles per liter or in pH units and used as a measure of the acidity of the solution. How to use hydrogen-ion concentration in a sentence.

Calculating the Hydrogen Ion Concentration From pH Now, dealing with scientific notation all the time to discuss hydrogen ion concentration is a little cumbersome. Instead, scientists use the pH scale. Here is the definition of pH: −log[H+]=pH ...
aqueous solution if the concentration of the other ion is known. THE USE OF pH TO MEASURE ACIDITY It is generally easier to express [H + ] in terms of pH. We shall define pH = -log[H + ]. Thus the pH of pure water would be pH = -log[H ...
pH calculation formula: pH = -log(1/H+) Where: H+: Hydrogen ion concentration in the solution H+ concentration of acid is depended on its pKa, for strong acid like HCl, its pKa=1, thus H+ concentration of 1 M HCl is also 1 M; for weak acid such as acetic acid, its pKa=...

When the pH of a solution changes from a value of 5 to a value of 8, by how much has the hydrogen ion concentration changed relatively speaking? Calculate the pH of a solution with an H3O+ concentration of 1.1 x 10-6 M. A solution of a strong acid has a pH of 3. What is the...
