酸 Acid

(重定向自酸度)
常见的强酸──硫酸的立体模型
El ácido perclórico es un ácido oxácido fuerte.

(有时用“HA”表示)的传统定义是当溶解在水中时,溶液中氢离子的浓度大于纯水中氢离子浓度的化合物。换句话说,酸性溶液的pH值小于水的pH值(25℃时为水的pH值是7)。酸一般呈酸味,但是品尝酸(尤其是高浓度的酸)是非常危险的。酸可以和碱发生中和作用,生成水和盐。酸可分为无机酸和有机酸两种。

  • 氢氯酸,硫酸和硝酸都被称为矿酸,因为它们从前都是透过矿物制得的。
  • 浓酸具腐蚀性,而稀酸则具刺激性(注意:稀氢氟酸也具有腐蚀玻璃的能力)。

Acid 酸

(重定向自Acidity)
Zinc, a typical metal, reacting with hydrochloric acid, a typical acid
Svante Arrhenius
Hydrochloric acid (in beaker) reacting with ammonia fumes to produce ammonium chloride (white smoke).

An acid (from the Latin acidus/acēre meaning sour) is a chemical substance whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals (like calcium) to form salts. An aqueous solution of an acid has a pH of less than 7 and is colloquially also referred to as 'acid' (as in 'dissolved in acid'), while the strict definition refers only to the solute. An acid usually contains a hydrogen atom bonded to a chemical structure that is still energetically favorable after loss of H (a positive hydrogen ion or proton). A lower pH means a higher acidity, and thus a higher concentration of positive hydrogen ions in the solution. Chemicals or substances having the property of an acid are said to be acidic.
