Which separation method is better suited for obtaining sugar from cane juice—filtration or evaporation?

Verified step by step guidance
1
Step 1: Understand the composition of cane juice, which is a mixture of sugar, water, and other impurities.
Step 2: Consider the principle of filtration, which is used to separate solids from liquids. Filtration would not be effective here because sugar is dissolved in the liquid, not present as a solid.
Step 3: Consider the principle of evaporation, which involves heating the solution to remove the solvent (water) and leave behind the solute (sugar).
Step 4: Recognize that evaporation is suitable for separating sugar from cane juice because it allows the water to evaporate, leaving the sugar behind.
Step 5: Conclude that evaporation is the better method for obtaining sugar from cane juice, as it effectively separates the dissolved sugar by removing the water.
