两性离子 Zwitterion(重定向自Internal salt)
![]() ![]() ![]() ![]() 两性离子(英语:zwitterion)是总电荷为0,电中性的化合物,又称内盐。虽然两性离子是电中性分子,但它却同时带有正负两种电荷,且带正电和负电的原子不同。有些化学家还认为两性离子中带正电和带负电的原子不应该是相邻的。此定义将诸如氧化胺的化合物排除。两性离子为极性,通常易溶于水,难溶于大部分有机溶剂。 两性电解质是具有酸性与碱性基团的分子(因此具备两性的特性),在特定pH值环境多半以两性离子存在。平均电荷为0的pH值称为该分子的等电点。

![]() ![]() ![]() ![]() In chemistry, a zwitterion (/ˈtsvɪtər.aɪ.ən/ TSVIT-ər-eye-ən; from German zwitter [ˈtsvɪtɐ] "hybrid" and formerly called a dipolar ion) is a neutral molecule with both a positive and a negative electrical charge. Multiple positive and negative charges can be present. Zwitterions are distinct from dipoles, at different locations within that molecule. Zwitterions are sometimes also called inner salts. |
