多元酸
多元酸，通常指在一个分子中可能放出多个质子（H）的酸。
如无机酸中的硫酸（H2SO4）、磷酸（H3PO4）等。
在有机化合物中主要指每一个分子含多个羧基的羧酸，如草酸（HOOCCOOH）、苹果酸（HOOCCH2CHOHCOOH）、顺丁烯二酸（HOOCCH=CHCOOH）等。这些化合物内不只有一个氢原子，它们也解离出多个离子。

Acid 多元酸
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.
