คำอธิบาย
In water, HCl produces hydrogen ions (H+) because it is an acid. When HCl donates a proton, the negatively charged chloride ion (Cl-) is left behind. However, the chloride ion (Cl-) is the conjugate base of hydrochloric acid (HCl) because it is left over after HCl donates a proton to water.
