# Does aqueous ammonia conduct electricity?

Aug 29, 2017

It does.......I do not have the data available.

#### Explanation:

Ammonia is a weak base, and undergoes some association in aqueous solution, according to the equation.....

NH_3(aq) + H_2O(l) rightleftharpoonsNH_4^+ +""^(-)OH

Now while this equilibrium lies to the left, there is some quantity of ammonium ion, and hydroxide ion in aqueous solution. And these charged particles can certainly conduct a charge. The extent of association may be estimated by the use of ${K}_{b}$ or ${K}_{a}$ for ammonium ion; and this should be available in your text.

${K}_{b} = \frac{\left[N {H}_{4}^{+}\right] \left[H {O}^{-}\right]}{\left[N {H}_{3} \left(a q\right)\right]}$
