Question

In a Brønsted-Lowry reaction, which of the substances is the acid? NH3(aq)+H20(l) -> NH+4(aq)+OH-(aq)

Answer 1

Answer:

$H_2O$

Explanation:

Here, we want to get the type of substances which are acids according to the Bronsted-Lowry definition

According to their definition, an acid donates or is the source of H+ ions in an acid-base reaction

Let us look at the reactants, we can see that while the ammonia molecule accepted a donation of hydrogen ion to become Ammonium ion, the water molecule lost a hydrogen ion to become the hydroxide ion

Thus, we can conclude here that the water molecule is the acid in the reaction
