The comparison between ammonium acetate and ammonium formate
Ammonium acetate and ammonium formate are often used as reagents in various chemical experiments and industrial processes. Although both contain ammonium root, their properties and uses are different. Try to analyze them.

Ammonium acetate has a peaceful nature. In solution, the degree of hydrolysis of acetate and ammonium root is slightly equal, so the solution is nearly neutral. Because of its mildness, it is often the first choice for biochemical experiments, such as protein precipitation, nucleic acid purification, etc. It can achieve the desired reaction without damaging the structure and function of biological macromolecules due to excessive acid-base environment. And it is also used in the field of organic synthesis. It can be used as a buffer to stabilize the pH of the reaction system and make the reaction proceed smoothly.

In contrast, ammonium formate is more active. The degree of hydrolysis of formate is different from that of ammonium root, causing the solution to be acidic. This acidic property makes it unique in specific reduction reactions. For example, in some catalytic hydrogenation reactions, ammonium formate can be used as a hydrogen donor to provide an active hydrogen source for the reaction and promote the reaction to the reduction direction. Furthermore, in the complexation reaction of some metal ions, ammonium formate can also form a stable complex with metal ions by virtue of its structural characteristics, which is used in the separation and purification of metal ions.

To sum up, ammonium acetate is mostly used in biochemical and acid-base environments where it is mild and neutral; ammonium formate is effective in reduction and complexation reactions due to its active acidity and unique hydrogen energy supply. Users should choose carefully according to specific needs and reaction conditions in order to make the best use and achieve the desired purpose.
