Your question is unclear....

Explanation:

Ammonium chloride, #NH_4Cl#, is a salt that is quite soluble in water...where it undergoes the acid-base equilibrium...

#NH_4Cl(aq) +H_2O(l)rightleftharpoonsNH_3(aq) + H_3O^+ +Cl^-#

O the other hand, there is no such beast as ammonium hydroxide...this is more of a trade-name. #NH_4OH-=NH_3*H_2O#

...ammonium hydroxide is therefore conc. ammonia...i.e. #NH_3(aq)#...a solution that is approx. #15*mol*L^-1# with respect to aqueous ammonia...and if you get a whiff of it, it brings tears to your eyes....
