In some circumstances, a water molecule will accept a proton and thus act as a Brønsted-Lowry base. We saw an example in the dissolving of HCl in H2O:
HCl + H2O(liquid) → H3O+(aq) + Cl−(aq)
In other circumstances, a water molecule can donate a proton and thus act as a Brønsted-Lowry acid. For example, in the presence of the amide ion (see Example 4 in Section 10.2 "Brønsted-Lowry Definition of Acids and Bases"), a water molecule donates a proton, making ammonia as a product:
H2O(liquid) + NH2−(aq) → OH−(aq) + NH3(aq)
In this case, NH2− is a Brønsted-Lowry base
