pH of fresh milk is ranges from 6.5 to 6.8. Which means, it is mild acidic.

But when it turns into curd, its pH decreases to 5 and less.

Because, fresh milk changes into curd.. due to the presence of bacterica called- Lactobacisllus. Lactobacillus makes the milk acidic, by releasing an acid - Lactic Acid.
