What is the pH level of raw milk? (MCAER 2017)

✔Explanation: Fresh, raw milk has a pH slightly below 7, making it mildly acidic. This is due to the presence of lactic acid and other organic acids, which are natural components of milk.

🔑KEY POINTS:
-Fresh milk has a pH ranging from 6.4 to 6.9.
-Over time, the pH of milk lowers further and it becomes even more acidic as the bacteria in the milk converts the sugar lactose into lactic acid.
-pH is a determined value, similar to temperature, based on a defined scale.
-pH stands for the “power of hydrogen” and the numerical value of pH is determined by the molar concentration of hydrogen ions (H+)³.
-The higher concentration of H+ ions is acidic nature.
