鹽橋(salt bridge)和氫鍵(hydrogen bond)的區別

鹽橋和氫鍵的關鍵區別在於鹽橋是一種電解液連接電化學電池中兩個半電池的管子，而氫鍵是兩個不同分子的兩個原子之間的吸引力。

鹽橋對於維持電化學電池的兩個半電池之間的連通性非常有用。肉眼可見。然而，氫鍵是一種化學鍵，維持兩個分子之間的連接，從而形成氫鍵。

什麼是鹽橋(a salt bridge)？

Salt bridge is a tube that contains an electrolyte (typically in the form of a gel), providing electrical contact between two soluti***. Therefore, this tube is important in connecting oxidation and reduction reacti*** of the galvanic cell. The purpose of using a salt bridge is to facilitate the electrochemical reaction reaching the equilibrium quickly. If there is no salt bridge, then one half-cell will accumulate positive charges, and the other half cell accumulates negative charges. C***equently, the generation of electricity stops. 鹽橋(salt bridge)和氫鍵(hydrogen bond)的區別

鹽橋主要有兩種類型：玻璃管橋和濾紙橋。玻璃管鹽橋是由玻璃製成的U形管，它含有電解液。在濾紙鹽橋中，有一張濾紙浸透了電解液。

什麼是氫鍵(hydrogen bond)？

氫鍵是兩個不同分子的兩個原子之間的一種吸引力。它是一種微弱的吸引力。但是，與其他類型的分子內作用力（如極性相互作用、非極性非極性相互作用（如範德瓦爾力）相比，氫鍵的強度更大。

Usually, hydrogen bonds form between polar covalent molecules. These molecules contain polar covalent bonds, which form as a result of the difference in the electronegativity values of the atoms that are in the covalent bond. If this difference is high, the highly electronegative atom tends to attract the bond electr*** towards itself. Thus, this creates a dipole moment where this highly electronegative atom gets a partial negative charge, whereas the other atom gets a partial positive charge. Then the bond becomes a polar covalent bond. When this molecule meets another molecule that has a dipole moment like this, the negative and positive charges tend to attract each other. And, this attraction force is called a hydrogen bond. 鹽橋(salt bridge)和氫鍵(hydrogen bond)的區別
