How does ammonium hydroxide react with sulfuric acid?
Please notice that the anions swap places from the left side to the right side; this makes it a Double Displacement reaction.
This is an acid base reaction...........
When we write
Now of course, as a weak base, there is SOME ammonium ion in solution according to the following equilibrium:
but the equilibrium lies to the left, and the dominant species in solution is
And so we could rewrite the reaction as:
We could isolate the salt
