Explanation:
Sugar is considered a pure substance because it cannot be separated into simpler substances by physical means. Let's explore each of the given options to understand why sugar is considered a pure substance.
a) It cannot be separated:
Sugar, in its pure form, cannot be separated into simpler substances through physical means such as filtration or evaporation. When sugar is dissolved in water, it forms a homogeneous mixture. However, this does not change the fact that sugar itself is a pure substance.
b) It can be separated:
This option is incorrect because sugar cannot be separated into simpler substances through physical means. If we try to separate sugar by filtering or evaporating the water, we will still end up with sugar as the final product.
c) It contains carbon and hydrogen:
While it is true that sugar contains carbon and hydrogen atoms, this fact alone does not determine whether a substance is pure or not. Many pure substances, such as water (H2O), also contain different atoms but are still considered pure.
d) It is crystalline:
This option is incorrect because the crystalline nature of a substance does not define its purity. Many pure substances, including sugar, can exist in both crystalline and amorphous forms.
In conclusion:
The correct answer is option 'a' because sugar cannot be separated into simpler substances through physical means. It is important to note that the purity of a substance is determined by its composition and not by its physical properties or characteristics.
