Ph Of Coca Cola: 5 Factors You Should Know!

What is the pH of Coca-Cola?

The pH level of Coca-Cola ranges from 2.5 to 4.5, which means it is acidic in nature. The acidic nature of coca-cola is due to the high levels of carbonic and phosphoric acid. Coca-Cola is so acidic that it can clean toilets and remove rust.

How can we determine the pH of Coca-Cola?

We can determine the pH of Coca-Cola by using a pH meter or pH strips.

Using a pH meter:

  1. Calibrate the pH meter.
  2. Pour Coca-Cola into a clean china dish.
  3. Immerse the pH meter electrode into the Coca-Cola sample.
  4. Wait for the pH meter reading to stabilize.
  5. Record the pH reading displayed on the pH meter.

Using pH strips:

  1. Obtain a pack of pH strips that are suitable for measuring the pH range of Coca-Cola.
  2. Pour Coca-Cola into a clean china dish.
  3. Dip the pH strip into the china dish.
  4. Remove the pH strip and compare the colour of the pH strip to the colour chart provided with the pH strips to determine the pH of the Coca-Cola.

Factors affecting the pH of Coca-Cola

There are several factors that can affect the pH of Coca-Cola. A few of them are mentioned below.

  1. Carbon dioxide (CO2): Carbon dioxide is the gas responsible for the fizz in Coca-Cola. Carbon dioxide dissolves in water to form carbonic acid, which lowers the pH of coca-cola.
  2. Phosphoric acid: Coca-Cola contains phosphoric acid, giving the drink a tangy taste. Phosphoric acid is also acidic in nature, which can lower the pH of the drink.
  3. Water quality: The pH of Coca-Cola can also be affected by the pH of the water used to make the drink. For instance, the high pH of water raises the pH of coca-cola.
  4. Temperature: The temperature of Coca-Cola can also affect its pH. At higher temperatures, carbon dioxide is less soluble in water, which can reduce the carbonic acid formation and raise the drink’s pH.
  5. Ageing: Over time, the concentration of carbon dioxide in the drink can decrease due to the loss of gas. It can cause the pH of the drink to rise as well.

What are the effects of Coca-Cola’s pH Level on Health?

Consuming low-pH beverages like Coca-Cola can have several adverse effects on our health. A few of them are mentioned below.

  • The low pH (acidity) of Coca-Cola can erode tooth enamel, which can lead to tooth decay and cavities. 
  • The low pH (acidity) of Coca-Cola can also interfere with the body’s ability to absorb calcium, which can lead to weakened bones over time.
  • In addition, the low pH (acidity) of Coca-Cola can also exacerbate acid reflux and other digestive issues.
