hydrogen ion
Acid's active particle
A hydrogen ion is a hydrogen atom that has lost its electron, leaving only a proton.
In chemistry, hydrogen ion concentration determines acidity—the more hydrogen ions in a solution, the more acidic it is.
The pH scale measures this: lower pH means higher hydrogen ion concentration.
Stomach acid has a high concentration of hydrogen ions.
