Ammonia is a weak base that reacts with water according to this equation:
$\text{NH}_{3} \left(a q\right) + \text{H}_{2} \text{O} \left(l\right) \rightleftharpoons \text{NH}_{4} ^{+} \left(a q\right) + \text{OH}^{−} \left(a q\right)$

Will any of the following increase the percent of ammonia that is converted to the ammonium ion in water?
