### 12.9 part d

Posted: Wed Nov 30, 2016 11:15 pm
Which of the following reactions can be classified as reactions between Bronsted acids and bases? For those that can be so classified, identify the acid and base. (Hint: It may help to write the net ionic equations.)

d) $NH_{4}I (am) + KNH_{2}(am) \rightarrow KI(am) + 2 NH_{3}(l)$
*Note: "am" indicates that liquid ammonia is the solvent.

How do you solve for this? Also, how would you write the net ionic equation? Thank you!

Good question. The first thing to note here is that the reaction takes place in liquid ammonia. That is, not in water (no hydronium ions).

Because NH4+ from NH4I is converted into NH3, there is a proton donated to the NH2-.
