Question

What bonds occur in `"ammonium hydroxide"`?

Answer 1

Not a good question............they look for `N-H`, and `O-H` bonds, and the ionic interaction between ammonium and hydroxide ion.....

Explanation:

`"Ammonium hydroxide"` is a bit of chimaera......I like to represent it as `H_3N*H_2O`, i.e. as aqueous ammonia. In aqueous solution ammonia undergoes reaction as a weak base.......

`NH_3(aq) + H_2O rightleftharpoonsNH_4^(+)+HO^-`

But the equilibrium lies to the left as written........

Concentrated ammonia is approx. `15*mol*L^-1` with respect to `NH_3(aq)`. Sometimes this is sold as `"ammonium hydroxide"`.
