One of the two water molecules acts as an Bronsted-Lowry acid and donates a proton to the other water molecule, which subsequently acts as a Bronsted-Lowry base.
Water can act as an acid or as a base in various chemical reactions, the most common two examples involving the ammonia and hydrochloric acid reactions.
NH3(aq)+H2O(l)⇌NH+4(aq)+OH−(aq)
Here water acts as a Bronsted-Lowry acid because it donates a proton to ammonia.
HCl(g)+H2O((l))⇌H3O+(aq)+Cl−(aq)
This time water acts a Bronsted-Lowry base because it accepts a proton from hydrochloric acid.
To be exact, in reactions that involve the transfer of protons, the term is actually amphiprotic.
hope it helps u bro!!

Amphoteric substance is that substance which has ability to donate as well as accept a Proton.
According to Bronsted -Lowry concept,bases stronger than water,tend to accept proton from it.Thus by donating proton,water acts as an acid.
H₂O + NH₃ <==> OH- + NH₄+
While acid stronger than water,like HCl ,tend to donate proton to water.Thus by accepting proton from such strong acids,water acts as base.
H₂O + HCl <===> H₃O+ + Cl-
Thus water can donate as well as accept proton and show amphoteric nature.
