pH Values of Some Common Substances – Check The List

Understanding pH Values

In chemistry, the term pH stands for “potential of hydrogen,” serving as a crucial quantitative measure of acidity or basicity within an aqueous solution. The pH scale, spanning from 0 to 14, delineates the concentration of hydrogen ions present in solutions.

  • pH values ranging below 7 signify acidity,
  • 7 denotes neutrality,
  • and values exceeding 7 indicate basicity.

The litmus test acts as a pivotal indicator to discern the nature of substances. When blue litmus paper turns red upon contact with a substance, it signifies acidity; conversely, if red litmus paper shifts to blue, it suggests a basic nature.

pH Scale

The pH scale is a logarithmic scale that measures the acidity or basicity of aqueous solutions. It ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 indicate a base.

pH Values List

The pH value serves as a gauge for the alkalinity or acidity of substances. As the pH value decreases, acidity escalates, while an increase indicates rising basicity. Below is a comprehensive table showcasing the pH Values of Some Common Substances:

  1. What is the pH range of fresh milk?

    The pH range of fresh milk typically falls between 6.5 and 6.7. This pH range indicates that fresh milk is slightly acidic. However, it’s important to note that the exact pH value can vary slightly depending on factors such as the type of milk (e.g., whole milk, skim milk), the diet of the dairy animal, and any processing or storage conditions.

  2. What is the pH range of vinegar?

    The pH value of vinegar generally falls around 2.4. This acidic pH level is primarily due to the presence of acetic acid, which is the main component of vinegar. However, the pH of vinegar can vary slightly depending on factors such as the type of vinegar (e.g., white vinegar, apple cider vinegar) and any additional ingredients or processing methods used during production.

  3. What is the pH range of lemon juice?

    The pH value of lemon juice typically ranges from 2 to 3. This acidic pH level is primarily due to the presence of citric acid, which is abundant in citrus fruits like lemons. However, variations in pH may occur depending on factors such as the ripeness and variety of the lemons used, as well as any processing methods applied.
