Is Sodium Acetate Organic?

Earlier, all the known organic substances were obtained from organisms such as animals and plants, so these compounds were called organic substances. By the 1820s, scientists used inorganic substances to artificially synthesize many organic substances, such as urea CO (NH2) 2, acetic acid CH3COOH, fat, etc., thereby breaking the concept that organic substances can only be obtained from organisms.

The German chemist Friedrich Wohler used the inorganic ammonium cyanate to synthesize an organic substance-urea {CO(NH2)2} in 1828.But this important discovery was not immediately recognized by other chemists, because cyanide Ammonium acid has not been prepared with inorganic substances. It was not until H. Kolbe synthesized acetic acid (CH3COOH) in 1844 and M. Berthelot synthesized oils and fats in 1854 that organic chemistry entered the era of synthesis, and a large number of organic substances have been synthesized by artificial methods .

The development of artificial synthetic organic matter makes people clearly realize that there is no clear boundary between organic matter and inorganic matter, but there are some differences in their composition and properties. In terms of composition, all organic matter contains carbon, most of which contain hydrogen, followed by oxygen, nitrogen, halogen, sulfur, phosphorus, etc. Therefore, chemists began to define organic matter as carbon-containing compounds.

So sodium acetate is organic. Organic matter refers to “carbon-containing compounds”, but CO, CO2, H2CO3, and carbonates should be removed. In other words, all other carbon-containing compounds are organic except for CO, CO2, H2CO3, and carbonate, .But be aware that not all organics are covalent compounds. Such as “ferrocene” and so on.

What Is Sodium Acetate Used For ?

1. Ussed for determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Auxiliary agent for acetylation Auxiliary agent, buffer, desiccant, and mordant.
2. Used as pH adjusting agent ,flavoring agent and also buffering agent . It can prevent bad odor and discoloration which could improve flavor of food as a buffering agent. It also can be used as a sour agent for food besides the anti-mildew effect.
3.Used as a scorch retarder for sulfur-regulated neoprene coking, and also as a crosslinking agent for animal glue.
4.Used for the addition of alkaline electroplating tin, while it is not a necessary ingredient because it has no obvious effect on coating and electroplating process
