low pH
Far from alkaline
Low pH describes acidity on the pH scale, where values below 7 indicate acidic conditions.
The lower the number, the more acidic: stomach acid has a low pH around 1-2, while lemon juice sits around 2-3.
The term appears in chemistry, skincare, and environmental contexts: Low pH levels in the lake are killing the fish, a low pH cleanser for sensitive skin.
