 is a medium-strong acid, stronger than phosphoric acid, for two main reasons. The first is that the carboxyl group is a relatively strong electron-withdrawing group. The introduction of an electron-withdrawing group will enhance the acidity of carboxylic acid (because the electron-withdrawing group reduces the negative charge density of the negative ion after ionization and stabilizes it). The second is that after oxalic acid is ionized once, it can form intramolecular hydrogen bonds, so the negative charge of the HC2O4 ion is actually divided equally by four oxygen atoms...

What is oxalic acid

Oxalic acid crystals Oxalic acid, also known as oxalic acid, is the simplest dibasic acid. Structural formula HOOCCOOH. It is generally colorless and transparent crystals, which are harmful to the human body, causing the pH balance in the human body to lose balance and affecting the development of children. Oxalic acid plays an important role in industry and can remove rust. Oxalic acid is found throughout nature, often in the form of oxalates in the cell membranes of plants such as barberry, oxalis, sorrel and sorrel,...
