What is Citric Acid, and what are its properties

Citric acid is a naturally-occurring organic compound used in many food and beverage products. It's found in citrus fruits such as oranges, lemons, limes, and grapefruits and has the molecular formula of C6H8O7. The sour taste of citric acid comes from its acidic nature; it has a pH of around 3, which is considered very acidic.

Citric acid is a popular food additive because it adds flavor, helps preserve the product, and acts as an antioxidant. It's often used as a flavor enhancer in candy, carbonated beverages, jams, and sauces. As an antioxidant, citric acid can also help preserve a product's shelf life. It can also act as an acidifier in some products, like baking powder and bread, to react with baking soda for a desired reaction.

Citric acid is also used around the home; it's often used in cleaning supplies and cosmetics due to its antibacterial and antifungal properties. Moreover, it's used in beauty products like facial cleansers and exfoliants because of its ability to help remove dead skin cells.
