phenolphthalein.
The acid that turns the indicator yellow in this scenario is carbonic acid, which is formed when carbon dioxide reacts with water. It causes the indicator to change color due to a decrease in pH levels.
Milk is around a 6.4-6.8 on the pH scale, and it is on the acidic side. universal indicator probably wont show up in milk but i'm guessing its yellowish. hopefully this answers your question c:
Lactic acid (or lactate, which is the anion of lactic acid) is the product of lactic acid fermentation.
it is the conversion of glucose into lactic acid
Milk contains lactic acid.

When organisms ferment sugars they usually produce lactic acid as a byproduct. This lactic acid production lowers the pH of the media the bacteria is grown in. The pH indicator changes the media color in response to the decreasing pH from the lactic acid production.
Lactate (also known as lactic acid) and NAD+

Lactic acidemia is the presence in excess of lactic acid in blood.
it is called lactose fermentation and it yields lactic acid + gas .....the acid can be recognized by chemical indicator ( Bromocresol) and the gas can be recognized my trapping the gas in an inverted tube ( Durham tube ).
acid as in lactic acid?
The two main types of lactic acid are L-lactic acid and D-lactic acid. They are optical isomers, meaning they have the same chemical formula but differ in the arrangement of atoms. L-lactic acid is the form produced in the human body during strenuous exercise, while D-lactic acid is produced by certain bacteria.

Glucose---Lactic Acid+ Energy
it is the conversion of glucose into lactic acid
No. Lactic acid is a different molecule than lactose. Molecular Formulas: Lactic Acid- C3H6O3 Lactose- C12H22O11 In addition, lactose is a sugar molecular while, as you may guess, lactic acid is an acid. When raw milk turns sour or becomes curdled, lactic acid bacteria are fermenting lactose into lactic acid.
