Supply Ammonia Solution(25%) Analytical reagent, chemical experiment use

Description

Basic information

Nature: colorless transparent liquid. For ammonia water solution. Volatile ammonia gas, has a strong pungent odor. Can miscible with ethanol. Strongly alkaline. Can absorb carbon dioxide from the air. Heat with sulfuric acid or other acid reaction. And volatile acid can form in the vicinity of smoke discharge. Relative density (d***5) 0.*0. Median lethal dose (rat, oral) **0mG/kG. Have corrosion. Tear.

Storage: keep in a cool, sealed. SCRC*****1

Use: analysis of reagent. Neutralizing agent. Alkaloid extract. Verification and determination of some elements (such as copper, nickel). To precipitate a variety of elements of the hydroxide. Ammonium compound. Detergent

Urgent rescue: inhalation: quickly from the scene to the fresh air. Maintain airway patency. If breathing is difficult, give oxygen. If the breath stops, immediately carry out artificial respiration.

Ingestion: oral intake of water gargle, to milk or egg white. Medical treatment.

Eye contact: immediately lift the eyelids, with large flow of water or normal saline rinse for at least *5 minutes. Medical treatment.

Fire extinguishing methods: fire extinguishing agent: water, spray water, sand.

Fire precautions: easy decomposition of ammonia gas, the higher the temperature, the faster the decomposition rate, can form explosive atmosphere.
