Bronsted-Lowry Model of Acids and Bases - help12
There are three similar versions of this question. Here is one of those versions:
Version 1:
When an acid donates a proton to another substance, it turns into its conjugate base. And when a base accepts a proton from another substance, it turns into its conjugate acid.
