Given That Sodium Bicarbonate Dissociates to Form Na⁺ and HCO₃^-

Given that sodium bicarbonate dissociates to form Na⁺ and HCO₃^- when mixed with water, which of these would be part of the explanation for taking bicarbonate (NaHCO₃) for excess stomach acid?

A) NaHCO₃ will not release hydrogen ions when mixed with water.
B) HCO₃^- will be a hydrogen ion acceptor.
C) Free hydrogen ions increase the acidity of a solution.
D) When bicarbonate ions combine with hydrogen ions, the pH increases.
E) All of these are necessary to fully explain how sodium bicarbonate works to counter excess stomach acid.
