Question

is sugar a pure substance

Answer 1

Sugar, specifically referring to sucrose, is considered a pure substance when it is in its crystalline form and not mixed with other substances. A pure substance has a uniform and definite composition. In the case of table sugar (sucrose), it has the chemical formula C₁₂H₂₂O₁₁ and consistent properties, making it a pure substance. However, if sugar is mixed with other ingredients, such as in a recipe or in powdered sugar that contains anti-caking agents, it would no longer be classified as a pure substance.
