PH of lime juice?
VerifiedAnswer: pH in the range of 2-3,
Explanation:
Lime juice is naturally acidic in nature, which is why it has a pH value that falls well below 7 on the pH scale. The typical pH range of lime juice is between 2-3, making it quite acidic and similar to other citrus fruits like lemons and oranges.
The acidic nature of lime juice comes from the presence of citric acid, which is the primary organic acid found in citrus fruits. Citric acid gives lime juice its characteristic sour taste and sharp flavor that we all recognize. When citric acid dissolves in water, it releases hydrogen ions (H+), which lower the pH and make the solution acidic.
To understand this better, let's remember that the pH scale ranges from 0 to 14, where 7 is considered neutral. Values below 7 are acidic, while values above 7 are basic or alkaline. With a pH of 2-3, lime juice is significantly acidic - in fact, it's quite close to the acidity level of stomach acid, which has a pH of around 1.5-2.
Several factors can influence the exact pH value of lime juice:
• The ripeness of the lime - fresher limes tend to be more acidic • The variety of lime being used • Growing conditions and soil quality • Storage conditions and age of the fruit
This high acidity makes lime juice useful in many practical applications. In cooking, the acidic nature helps preserve food and adds flavor. The acid can also help break down proteins in marinades, making meat more tender. Additionally, the acidic environment created by lime juice can inhibit the growth of harmful bacteria, which is why it's often used in food preservation.
It's interesting to note that despite being acidic outside the body, lime juice can have an alkalizing effect once metabolized. This happens because the citric acid gets broken down during digestion, leaving behind alkaline mineral salts that can help balance the body's pH levels.
