A protein called casein, present in milk, forms a coagulum in the presence of an acid. This may result from the splitting of some of the phosphate that had been esterified to the casein and also from some proteolysis of peptide bonds in the casein molecules.

Curd is more acidic than milk is this true?
curd is more acidic than milk .Because when milk is changed to curd it's pH value decreases due to the formation of lactic acid.
Is formation of curd a chemical change or a physical change?
Setting of curd is a chemical change b'coz when lactobacillus bacteria comes in contact of milk they convert the milk to curd due to some biochemical reasons.
Does pH of milk change as it spoils?
The pH of milk could change as it spoils, depending upon the microbes that are making it spoil.
How does temperature affect the pH level of milk?
Temperature affects the pH balance of milk when heated milk becomes sour turning it more acidic with a pH balance of 7.52 where as curdled milk is more of a base because they make cottage cheese out of it. It has a base of 4.7254
What is the pH of boiled milk?
Milk has a pH of about 6.4 to 6.8. Skim milk has a pH of about 5.1 to 5.4.
If pH of milk is 6 then what will be the pH of curd?
no change

What is the useful microorganism present in curd?
Lactobacillus casei is the bacterium present in curd. It produces lactic acid, which in turn reduces the pH and coagulates milk proteins (primarily casein) forming curd.
Why does bacteria affect the pH value of milk?
as the bcteria chaanges the ph to an acid thus turning the milk sour thereby changing the ph value.
Does pH of milk change as it spoils?
The pH of milk could change as it spoils, depending upon the microbes that are making it spoil.
Why it is necessary to add a small amount of yogurt to convert milk into yogurt?
Yogurt converts the milk sugar to lactic acid, driving the pH down. The low pH causes the milk proteins to coagulate into a soft curd. So basically yogurt is milk transformed by harmless bacteria.
How does temperature affect the pH level of milk?

When milk is converted into curd what causes the sour taste?
A bacteria called lactobacilus converts lactose into Lactic acid thus making it sour. Lactic acid buildup due to bacterial activity causes the pH of the milk to drop. Once the pH drops below pH 4.6, the casein proteins coagulate and forms a curd. The curdling is due to the milk becoming sour.
What will happen if the milk spilled in the vinegar?
Curdled milk.
Does adding more sugar to milk change the pH?
Ph level of sugar is 5.5
How does milk of magnesia react to stomach acids?
Milk of magnesia does not act as a good buffer because the level of ph doesn't change rapidly. The ph needs to change for anything, acid or base.
