A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
Answer Yes, milk is regarded as a mixture and not a pure substance. To be more specific, milk is a colloidal mixture. In a colloidal mixture, particles are suspended freely in the solvent. In milk, the particles consist of fatty acids, proteins, mineral ions etc. in a solvent of water (constituting most of the solvent part). Colloidal mixtures exhibit a typical effect called the Tyndall Effect. You can demonstrate Tyndall Effect in your room itself. Take a jar containing a mixture of milk and water in an approximate ratio of 5:1. Place it in your room and darken the room by turning off all lights and putting the curtains. Apply a focus of torch light on the mouth of the jar. The shine produced as such is called the Tyndall Effect, which is exhibited only by colloidal mixtures like milk, BLOODY ETC. It is a mixture of many, many different substances. it is a mixture so,it is not a pure substance
it s pure liquid.
It's a pure substance.
Mixture
Milk is a complex mixture.
A pure substance by definition cannot be a mixture. Pure in chemistry means only one substance is present.
Milk is considered a mixture rather than a pure substance because it is composed of different compounds such as water, proteins, fats, and sugars.
It tells you the elements and the proportions of those elements that are present to make the pure substance.
Magnesium is an element, so it's a pure substance.

Chocolate pudding would be considered a pure substance.
A pure substance has a specific density that remains constant regardless of the amount of substance present. An impure substance may have a density that varies depending on the amount and type of impurities present in the substance.
There is no other substance present and so it is a compound a pure substance just as NaCl - salt is.
Ammonia is pure substance. It is a molecule with formula NH(3).
