Coconut milk is not a pure substance; it is a mixture. It is made by blending the grated meat of coconuts with water, resulting in a liquid that contains fats, proteins, carbohydrates, and water, along with other compounds. Because it consists of various components combined together, it does not meet the criteria of a pure substance, which is defined as having a uniform and definite composition.
