Formic acid and other acids have different chemical properties and uses, so they need to be distinguished and distinguished in actual production and use. Let's briefly introduce the basic knowledge of formic acid and other acids

Formic acid is a colorless, pungent liquid with the chemical formula HCOOH, soluble in water. Formic acid is mainly used as a bactericide, disinfectant, and can also be used in fields such as dyes and pharmaceuticals. Other common acids include sulfuric acid, hydrochloric acid, acetic acid, etc., each with its own characteristics and uses

To distinguish between formic acid and other acids, one can first make a preliminary judgment by observing their appearance and odor. Formic acid is a colorless liquid with a pungent odor; And sulfuric acid is a colorless liquid with no obvious odor; Hydrochloric acid is a colorless liquid with a pungent odor; Acetic acid is a colorless liquid with a sour vinegar taste. Therefore, the difference between formic acid and other acids can be preliminarily determined through odor identification

Chemical reagents can be used for analysis. The reaction between formic acid and ammonium bicarbonate produces ammonia gas, which is a simple method for identifying formic acid. Place a small amount of formic acid and ammonium bicarbonate solid in the measuring tube, seal it with a rubber stopper, and heat it with a flame. If there is a white mist gas produced at the tube mouth, it indicates that the sample contains formic acid

In addition, in actual production and use, professional instruments can also be used for analysis and identification. For example, the structure of compounds in the sample can be analyzed using an infrared spectrometer to determine whether they contain formic acid

Overall, formic acid and other acids have significant differences in appearance, odor, and chemical properties. We can make preliminary judgments by observing odor and chemical reagents, or accurately identify them with professional instruments. Accurate identification of formic acid and other acids is crucial in practical production and use, as it can effectively prevent chemical accidents and ensure personal and property safety.
