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

formic acid is a colorless, irritating liquid, chemical formula HCOOH, soluble in water. Formic acid is mainly used as germicide, disinfectant, also can be used in dyes, drugs and other fields. Other common acids include sulfuric acid, hydrochloric acid, acetic acid, etc., which have their own characteristics in nature and use.

to distinguish between formic acid and other acids, you can first make a preliminary judgment by observing their appearance and odor. Formic acid is a colorless liquid with a pungent smell; sulfuric acid is a colorless liquid with no obvious smell; hydrochloric acid is a colorless liquid with a pungent smell; acetic acid is a colorless liquid with an acetic acid smell. Therefore, the difference between formic acid and other acids can be preliminarily judged by the discrimination of odor.

can be analyzed using chemical reagents. Formic acid reacts with ammonium bicarbonate to produce ammonia, which is a simple method to identify 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 flame. If there is white mist gas at the nozzle, it means that the sample contains formic acid.

In addition, in actual production and use, it can also be analyzed and identified by professional instruments. For example, the structure of the compound in the sample can be analyzed by infrared spectroscopy to determine whether it contains formic acid.

In general, formic acid and other acids have obvious differences in appearance, odor and chemical properties. We can make preliminary judgments by observing odor and chemical reagents, and can also use professional instruments for accurate identification. In actual production and use, it is very important to accurately distinguish formic acid and other acids, which can effectively avoid chemical accidents and protect personal and property safety.
