Question

fresh milk has a pH of 6 how do you think that pH will change as it turns into curd​

Answer 1

curd is acidic ( it contains lactic acid) and acidic substances have ph value much lower than 7 ( say 4or 5 in case of lactic acid ) so ph of milk will fall down as it changes into curd

Answer 2

• pH measures the acidicity of a substance.
• pH of fresh milk is 6 when it changes to curd it becomes 4.5 - 5.5
• pH decreases as milk changes to curd.
• this is because of the formation of lactic acid which is acidic in nature.
