The pH value of the curd is:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. lower than the pH value of milk.
Curd has a slightly acidic pH, usually ranging from 4.5 to 5.5, which is lower than the pH of milk (which is typically around 6.5 to 7). The acidity in curd is due to the fermentation process, where lactic acid is produced by bacteria that convert lactose (milk sugar) into lactic acid. This drop in pH gives curd its tangy taste and thicker texture.
