Ph ion water
Webb1 apr. 2024 · The pH scale runs from 0 to 14, with 7 being a neutral pH. Anything higher than 7 is basic (or alkaline) and anything lower than 7 is acidic. The pH scale is an inverse of hydrogen ion concentration, so more hydrogen ions translates to higher acidity and a lower pH. Carbon dioxide and seawater Webb6 jan. 2024 · To do this, use our hydrogen ion concentration calculator: Enter the pH of 3.5 into the "pH" field.
