Ammonium Hydroxide mixed with Water?

What chemical reaction will it undergo if ammonium hydroxide is mixed with tap water? Furthermore, does the water with ammonium hydroxide can produce a hazardous fumes or vapors?

Thanks.

Update:

So it seems you should have a wide area or a proper ventilation to avoid ammonia fumes?! right?

Update 2:

Wow! Thanks! The water has already been chlorinated

    This may be a trick question. Ammonium Hydroxide is Ammonia gas (NH3) dissolved in water.

    Concentrated NH4OH (ammonium hydroxide) will simply become diluted when added to tap water, unless the water has been chlorinated and/or treated with fluoride. If this is the case, compounds called Chloramine* and Fluoramine* may result. This is the reason that Campden Tablets are added to aquarium water. The Campden tablets remove the halogenated amines* like chloramine and fluoramine to prevent harming the fish.

    And yes, the halogenated amines are toxic.

    * the halogens react with the ammonium ion to produce these halogenated amines.

    This will be the reaction

    NH3 + H2O -----> NH4 + OH

    Well it does produce ammonia, so yeah there's ammonia vapours.
