Acidity of Vinegar

The acidity of vinegar is derived based on its pH levels and is calculated by a formula that reveals its acidic balance. Learn about not just the formulae behind this ingredient's content but also its health benefits.
Vinegar is most commonly known as a food ingredient to balance taste by adding a hint of acidity into it. Lemon juice is used as a vinegar substitute, commonly used in pastries as well to give it that sour punch, that highlights the essence of taste. The acidity levels of vinegar and lemon juice are very close to each other, with not much of a difference present in their pH levels. We look into how the pH level of vinegar is calculated, where lemon juice is 2.3 in its pH level. We will get into how the pH level of vinegar is derived and what it means to fall in that decimal range.

pH Level of Vinegar Calculation

The density of vinegar is calculated using a 'hydrometer', which is an instrument used to calculate the right degree of gravity contained within a solid or liquid. Vinegar has 5% acetic acid content where its density amounts to '1.01 grams/milliliter'. The abbreviation 'pH', refers to 'potential hydrogen', where the amount of hydrogen ions is determined in that format. The scale of pH levels ranges from 1 to 14, where elements that fall below the number 7 in pH levels, is neutral (basic / alkaline) in nature, with a high concentration of hydrogen ions. If levels fall lower than the pH level 7, then these are acidic in nature, where hydrogen ions are low. To calculate the pH of vinegar, we apply the following formulae to get its result.


(H+) Hydrogen concentration
(OH-) Hydroxyl Ion

CH3COOH (acetic acid) ↔ CH3COO- (acetate) + H+

pH = -log [H+]

pH = -log 3.98x10-3

pH of vinegar = 2.4

Health Benefits of Vinegar

The benefits of vinegar not only aid one in health related problems, but also come in use for many other purposes as well.
  • Apple cider vinegar is known to lower blood pressure levels.
  • Helps eliminate bad breath and infections in the mouth, by gargling with water and vinegar.
  • Helps treat dandruff.
  • Mixing vinegar and honey together will help you dissolve crystal deposits on one's joints during arthritis. It will ease the pain if not completely cure your malady.
  • Using vinegar to treat warts is helpful, due to its salicylic acid properties.
  • Helps give hair more shine.
  • Reduces cholesterol in the body.
  • A teaspoon or more of vinegar can help stop hiccups.
  • Can be used to treat sunburns.
  • Diminishes food cravings.
  • Absorbs fat deposits in the body, and rids it from the system.
  • Helps counter the effects of heart disease and even cancer.
  • Helps keep one's weight in check.
  • Relieves the state of insect bites or stings.
  • Dabbing apple cider vinegar on the urethra can help with urinary tract infection.
  • Can help prevent ulcers when ingested.
  • Strengthens the immune system.
  • Helps in digestion and bowel movement.
  • Increases insulin sensitivity in diabetics suffering from type 2 diabetes.
The benefits of this acidic liquid do sound helpful in many areas of one's everyday problems, but like all things, you need to use it in limited and sparing amounts, since at the end of the day it is an acid. Have a healthy tomorrow.
