Consider the following statements: 1. The pH of curd is lower than that of milk. 2. Curd is more acidic than milk. 3. A substance with a pH around 8 tastes sour. Which of the statements given above is/are correct?

Explanation

During curd formation, bacterial fermentation produces lactic acid and lowers the pH relative to the original milk. Curd is therefore more acidic. A pH near 8 is mildly alkaline and does not indicate the sour acidic character asserted in statement 3. Only 1 and 2 are correct.
