25% ammonia solution diluted to 7%
Thread Content
I’ve come across a device that requires 7% concentration ammonia. I would like to ask the experts: is heat released when 25% ammonia is diluted to 7% concentration? How much heat is there? Can someone help simulate it? Thank you very much

The dissolution of ammonia in water is an exothermic process; it is the process by which NH3 combines with H2O to form the more stable NH3.H2O. When ammonia water is diluted, a small amount of free ammonia may continue to undergo hydration, but this amount should be very small, and no significant heat release should occur.
I’ve seen that in some companies, it’s the workers themselves who prepare it – they simply do a quick calculation based on volume and concentration before starting work.
