Term
ammonium hydroxide
 Definition

NH4OH

 

This chemical does not actually exist; it is an old-fashioned name for the solution that is formed when gaseous ammonia, NH3, is dissolved in water.  It was thought that the following reaction occurs:  NH3 + H2O → NH4OH

 

This reaction does not occur, and all we have is ammonia (NH3) dissolved in water.  The solution is best called "aqueous ammonia."
