哈米特酸度函数哈米特酸度函数 (H0) 是一种用于衡量高浓度酸酸性的指标,包括超强酸。它是由物理有机化学家路易斯·普拉克·哈米特(Louis Plack Hammett)建议使用的 ,这也是最著名的酸度函数 ,它对于超出pH值范围的情况是很有用的。 在这样高浓度的酸性体系中,由于变化的活度系数,类似于Henderson-Hasselbalch方程的简单近似不再有效。哈米特酸度函数使用领域很广,例如物理有机化学中研究酸催化反应,因为其中一些反应所用的酸浓度很高,甚至是纯的。

Hammett acidity function 哈米特酸度函数The Hammett acidity function (H0) is a measure of acidity that is used for very concentrated solutions of strong acids, including superacids. It was proposed by the physical organic chemist Louis Plack Hammett and is the best-known acidity function used to extend the measure of Brønsted–Lowry acidity beyond the dilute aqueous solutions for which the pH scale is useful. |
