Mix Bleach Ammonia Water Reactions
On the change of bleaching, ammonia water and water
Bleaching water and ammonia water are all commonly used chemicals in the world. Bleaching water, with strong oxidizing properties, is mostly used for bleaching and disinfection; ammonia water is alkaline and is also widely used in cleaning, chemical and other industries. If the two are mixed with water, the reaction is quite complicated and needs to be studied in detail.
The main component of bleaching water is sodium hypochlorite ($NaClO $). For ammonia water, the solute is ammonia ($NH_ {3}\ cdot H_ {2} O $). When bleaching water and ammonia water are mixed with water, sodium hypochlorite can chemically react with ammonia. First, sodium hypochlorite will oxidize ammonia, and the valence state of nitrogen in ammonia will change. Common reactions can generate nitrogen ($N_ {2} $), chloramine (such as $NH_ {2} Cl $, etc.) and other products. The chemical equation of
to generate nitrogen is roughly as follows: $3NaClO + 2NH_ {3}\ cdot H_ {2} O = 3NaCl + N_ {2}\ uparrow + 5H_ {2} O $. When the reaction is violent, there will be a gas escape, which will be in a closed space, or cause the air pressure to rise, which is dangerous for safety.
The reaction of chloramine, such as $NaClO + NH_ {3}\ cdot H_ {2} O = NH_ {2} Cl + NaOH + H_ {2} O $. Chloramine also has certain oxidation and toxicity. And chloramine will be further hydrolyzed in water, affecting the water quality, releasing irritating gases, and damaging the human respiratory tract, eyes, etc.
Furthermore, bleaching water is mixed with water, and sodium hypochlorite is hydrolyzed, making the solution alkaline. Ammonia is also alkaline. After mixing the two with water, the alkalinity of the solution may change, affecting many chemical reactions. If there are other substances in the environment, such as some metal ions, it may also catalyze the reaction between bleaching water and ammonia water, accelerating the formation of harmful products.
Because bleaching water, ammonia water and water are mixed, the reaction is complex and harmful. Or cause gas to escape, produce harmful substances, endangering personal safety and the environment. Therefore, when using these two types of chemicals, be careful not to mix them at will to avoid unexpected disasters.
