Expert Solution
Step 1 Introduction
Bronsted Lowry Acid base theory states that the acids are species that donates a proton while the bases accept a proton. Conjugate acids are those which are formed when a base accepts a proton, while conjugate bases are those which are formed when an acid loses a proton.
