Dissolving Equation for NH3: NH3 + H2O = NH4+ + OH-

AI Thread Summary
The dissolution equation for ammonia (NH3) in water is NH3 + H2O ⇌ NH4+ + OH-. This reaction involves ammonia accepting a proton (H+) from water, resulting in the formation of ammonium (NH4+) and hydroxide (OH-) ions. While this reaction does occur, it is important to note that the equilibrium lies significantly to the left, indicating that most ammonia remains undissociated in solution. The discussion highlights the confusion around the nature of ammonia's dissolution and its interaction with water. Understanding this equilibrium is crucial for accurately representing ammonia's behavior in aqueous solutions.

Homework Statement


write the dissolution equation for NH3(ammonia)

The Attempt at a Solution



I think that the NH3 steals a proton(H+) from a water molecule therefore creating a hydroxide ion and a ammonium ion is this correct? here is what i have done.

NH3(s)----H20---->NH4+(aq) + OH-(aq)

I may have solved this on my own but I like to be certain and I won't get a chance to ask my instructor before I must hand my assignment in. Thanks!

That's a little bit tricky. In general, ammonia just dissolves, and it doesn't react with water.

Reaction you wrote does occur, but the equilibrium is far to the left.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
