Milk is generally neutral in pH, typically around 6 to 7, so it does not significantly affect blue litmus paper. When blue litmus paper is exposed to milk, it will remain blue, indicating that there is no acidic property present to change its color. If the milk were to spoil and become acidic, it might turn the blue litmus paper red, but fresh milk will not.
Milk of magnesia is basic, so it will turn red litmus paper blue and have no effect on blue litmus paper.
Milk of magnesia is chemically known as magnesium hydroxide. Although this compound isn't very water soluble, the small amount that does dissolve acts as a base. Thus, milk of magnesia is somewhat basic, and litmus paper would turn blue if exposed to it.
Sour milk is acidic. Red litmus paper should not change.The sour part of sour milk is lactic acid. As litmus paper turns red when exposed to acidic compounds, litmus paper that is already red should not react when exposed to lactic acid.
Evaporated milk is a white-colored liquid, so if it turns red under red litmus paper, it indicates that the milk is acidic. This change in color suggests the presence of acidic substances in the evaporated milk, which can be detected by red litmus turning red in an acidic environment.
If Bacillus subtilis is inoculated into litmus milk, it will likely grow and metabolize lactose, forming acid as a byproduct. This metabolism will cause the litmus milk to turn pink or purple as the pH decreases due to the production of acid. The milk may also show coagulation due to acid production.
Milk of magnesia is basic, so it will turn red litmus paper blue and have no effect on blue litmus paper.
Red litmus paper will turn blue in the presence of milk, indicating a basic pH. Blue litmus paper will remain blue, as milk is not acidic enough to change its color.
Blue litmus paper remains blue when dipped in milk of magnesia because milk of magnesia is basic in nature.
blue
red
the color of the litmus paper does not change.
Milk of magnesia is chemically known as magnesium hydroxide. Although this compound isn't very water soluble, the small amount that does dissolve acts as a base. Thus, milk of magnesia is somewhat basic, and litmus paper would turn blue if exposed to it. Nice....
i think its neither a base nor a acid . i thinks its neutral

Litmus paper is not typically sufficient for testing the pH of milk. To accurately test the pH of milk, you can use a pH meter or pH strips that are specifically designed for testing the pH of food and beverages. These tools provide more accurate and precise measurements than litmus paper.
Litmus milk medium is skim milk to which the dye litmus has been added. Litmus is both a pH indicator and a redox indicator. It is pink at pH < 4.5, purple in middle pH's and blue at pH > 8.3. As a redox dye, in the absence of oxygen (reduced state) it's colorless (white due to milk) and in the presence of oxygen (oxidized state) it is purple.
