In its pure form, phosphoric acid is a strong acid with a pH value less than 1. However, when diluted in water, its pH can increase significantly. This characteristic is particularly important in food and beverage industries, where phosphoric acid is often used as a flavoring agent and acidulant. For example, in soft drinks, phosphoric acid not only contributes to taste but also acts as a preservative. The pH of these beverages is typically between 2 to 4, creating an environment that inhibits the growth of harmful bacteria without compromising flavor.
