As milk ferments, the pH decreases (becomes more acidic). This change occurs because lactate (lactic acid) is produced as a result of carbohydrate metabolism.

Why milk magnesia is basicity in the pH scale?
the pH of milk of magnesia is important because it lowers the pH of the acid in your stomach
When using the phenol red carbohydrate broth fermentation test at what pH is the pH indicator yellow?
below 6.8
Does the pH change during the course of the fermentation?
the medium becomes acidic
What is the pH of milk at 25 degree c?
Cow's milk (fresh, whole milk) has a pH ranging from 6.4 to 6.8
Fresh milk has a pH of 6. How do you think the pH would change as it became sour.Explain why?
The pH goes lower in sour milk. See Related Links.
What is the relation between pK and pH?
At half equivalence (half neutralisation) pH=pK.
Why is spoiled milk not used for yogurt making?
Fresh milk must be used because the fermentation process must lower the pH of the milk gradually. Chemicals are also released during the fermentation process that improves the taste of the yoghurt. If spoiled milk is used for yoghurt, the taste and the texture would not be correct.
Is there any relation between forced vortex and water pH?
No.
What is the pH level of milk?

What is the pH level in yeast fermentation?
what is the pH level of yeast?
Is milk an acid or alkali?
Milk is mildly acidic, pH ~ 6.5 However, when milk goes sour, it forms lactic acid , which has a pH ~ 3
What is PH for 1 percent milk?
milk is very slightly acid. it's pH is somewhere between 6.5 and 6.7 milk's fat does not influence it's acidity.
Why does acid clot appear pink or white with a pink band at the top?
Litmus milk is an undefined medium consisting of skim milk and the pH indicator azolitmin. Azolitmin is purple between pH of 4.6 and 8.2. It turns pink when pH reaches 4.5 and blue at a pH of 8.3. Lactose ferminatation turns the litmus pink due to acidity. If litmus is reduced during lactose fermentation it will turn the medium white. Acid may cause an acid clot this is due to the casein precipitating. Heavy gas production can cause stormy fermentation, this is due to the breaking up of the clot.
What is the relation between pH and quality of soap?
Soap, no matter how good a soap is, is soap. The pH will never change in relation to the quality of soap. It is a 'basic' pH'ed molecule (NaOH).

What is the relation between pH value and nature of the solution?
The nature of the solution be it acidic or basic will determine the PH value of the given solution.
