A chemical will become acidic or non-acidic depending on the release of H+ ions in water. Acids are chemicals that, when they dissociate with water, produce hydrogen ions. Some substances have an acidic nature as they dissociate in an aqueous solution, producing hydrogen ions (acids like HCl, and HNO3)
Hydrogen is present in substances that are similar to glucose or alcohol, but they do not exhibit acidic characteristics. The hydrogen in them does not separate from like the hydrogen in the acids, in actuality. When they dissolve in water, they won’t separate to create hydrogen ions.
