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

[synergix]

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.
