hydrogen ions
pH scale determinants
Hydrogen ions are hydrogen atoms that have lost their electron, leaving only a proton.
In chemistry, they determine acidity—the more hydrogen ions in a solution, the more acidic it is.
The pH scale measures hydrogen ion concentration: lower numbers mean more hydrogen ions, higher acidity.
Pure water contains equal amounts of hydrogen and hydroxide ions, giving it a neutral pH of 7.
