DIPROTIC ACID在英语中的意思是什么？

二恶酸

Diprotic acid

二次酸是一种酸如H 2 SO 4，其在其分子结构内含有每分子能够在水中分解的两个氢原子。 二元酸的完全解离与硫酸的形式相同：H2SO4→H + + HSO4-Ka = 1×103 HSO4-→H + + SO42-Ka = 1×10-2解离不会一次发生，因为 解离的两个阶段具有不同的Ka值。 在硫酸的情况下，第一个解离将完全发生，但第二个解离不会。 关于滴定实验，二元酸特别值得注意，其中pH与滴定剂体积曲线将清楚地显示酸的两个等同点。 这是因为酸分子上的两个可离子化的氢原子不同时离开酸。 常见的双重酸包括在苹果和樱桃中发现的苹果酸和葡萄和菠萝中发现的酒石酸。 另一种二价酸是尿酸，其pKa1为5.4，pKa2为10.3，因此在生理pH下单独充电。

A diprotic acid is an acid such as H2SO4 that contains within its molecular structure two hydrogen atoms per molecule capable of dissociating in water. The complete dissociation of diprotic acids is of the same form as sulfuric acid: H2SO4 → H+ + HSO4− Ka = 1 × 103 HSO4− → H+ + SO42− Ka = 1 × 10−2 The dissociation does not happen all at once due to the two stages of dissociation having different Ka values. The first dissociation will, in the case of sulfuric acid, occur completely, but the second one will not. Diprotic acids are of particular note in regards to titration experiments, where a pH versus titrant volume curve will clearly show two equivalence points for the acid. This occurs because the two ionization capable hydrogen atoms on the acid molecule do not leave the acid at the same time. Common diprotic acids include malic acid, found in apples and cherries, and tartaric acid, found in grapes and pineapples. Another diprotic acid is uric acid, which has a pKa1 of 5.4 and a pKa2 of 10.3, and is therefore singly charged at physiological pH.
