What To Know

The tangy, zesty flavor of lemon juice is a beloved addition to countless dishes and beverages. But beyond its culinary appeal, there’s a scientific aspect to this citrus wonder: its acidity. You might have heard the term “pH” thrown around, especially in discussions about acidity. So, what is the pH of lemon juice, and why should you care?
Understanding pH: The Scale of Acidity and Alkalinity
pH stands for “potential of hydrogen” and measures the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. Solutions with a pH below 7 are acidic, while those above 7 are alkaline (also known as basic). The lower the pH value, the stronger the acid.
Lemon Juice: A Citrus Powerhouse of Acidity
Lemon juice is a naturally acidic solution. Its pH typically ranges from 2.0 to 2.5. This makes it significantly more acidic than many other common substances, including vinegar (pH 2.4-3.4) and orange juice (pH 3.3-4.0).
The Source of Lemon Juice’s Acidity: Citric Acid
The primary contributor to lemon juice’s acidity is citric acid, a naturally occurring organic compound. Citric acid gives lemons their characteristic tart flavor and plays a crucial role in their preservation. It’s also found in other citrus fruits like oranges and grapefruits, though in lower concentrations.
