from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is more acidic...
The pH scale measures the acidity of a substance. It ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most basic. For example, battery acid has a pH of 0, water has a pH of 7, and drain cleaner has a pH of 14. The pH balance of dif...
Watch this video for a straightforward explanation of pH and its logarithmic scale.BuffersSo how can organisms whose bodies require a near-neutral pH ingest acidic and basic substances (a human drinking orange juice, for example) and survive? Buffers are the key. Buffers readily absorb excess H...
对于常见的化合物,通常我们可以在一些较权威的网站(比如Drugbank、HMDB等)查询pKa值。在查询时通常会发现有两个值,pKa(strongest acidic)和pKa(strongest basic),这是因为一个化合物含有多个电离基团,存在多个电离平衡,故有不止一个pKa值,这里往往只是展示了最强酸基团和最强碱基团的pKa值。 对于pKa未知的化合物,可...

pH Scale: An Explanation The pH scale measures the acidity or basicity of a solution. It ranges from 0 to 14, with 7 being neutral. A solution with a pH of less than 7 is considered acidic, while a solution with a pH greater than 7 is considered basic. The pH scale is logarithmic,...

想到酸,許多人會用sour「酸的」來形容味道,但在化學上會用形容詞acid或acidic表達「酸的、酸性的」。那acid也可以直接當名詞,常常搭配其他名詞表示某種酸,如stomach acid 胃酸、fatty acid 脂肪酸、amino acid 尿酸等。舉個例子: Many woodland plants prefer acid soils.(許多林地植物偏好酸性泥土。) ...
