The burning sensation associated with heartburn is a result of the acid of the stomach leaking through the muscular valve at the top of the stomach into the lower reaches of the esophagus. What I've experienced: Because Perchloric Acid is a strong acid, it's Conjugate Base, ClO4- is Weak, and is negligible because it's not that basic. Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
