The juice that is squeezed from an orange is classified as a mixture rather than a pure substance. This is because orange juice contains various components that can vary in proportion depending on the specific orange.
To elaborate, when you juice an orange, you get a combination of water, sugars, acids, and other compounds like vitamins, minerals, and flavor compounds. These components do not have a fixed ratio and can change with different oranges. For example, some oranges may produce juice that is sweeter or more acidic than others.
In contrast, a pure substance has a uniform composition and specific properties throughout, such as distilled water or sugar. Since orange juice can have different characteristics based on the type of orange and how the juice is extracted, it clearly fits the definition of a mixture.
