Solution: Separation of Sugar in Water

Introduction
When a substance dissolves in another substance, it forms a solution. In the case of sugar in water, sugar particles dissolve in water particles to form a sugar-water solution. However, it is possible to separate the components of this solution using different methods. One of the most effective methods for separating sugar from water is evaporation.

Explanation

1. Filtration
Filtration is a method used to separate insoluble solids from liquids or gases using a filter. In the case of sugar in water, both sugar and water are in a dissolved state, so filtration cannot be used to separate them.

2. Sedimentation
Sedimentation is the process of settling down of solid particles in a liquid due to gravity. It is used to separate insoluble solids from liquids. However, since sugar is completely dissolved in water, there are no solid particles present that can be separated by sedimentation.

3. Decantation
Decantation is a method used to separate a liquid from solid particles that have settled at the bottom of a container. Since sugar is in a dissolved state in water, there are no solid particles to be separated by decantation.

4. Evaporation
Evaporation is the process of converting a liquid into a gas by heating it. In the case of sugar in water, the water can be separated from sugar by heating the solution. As the water evaporates due to the heat, sugar particles are left behind, resulting in the separation of sugar from water.

Conclusion
In conclusion, among the given options, the most suitable method for separating sugar from water is evaporation. By heating the sugar-water solution, the water evaporates, leaving behind the sugar particles. This process is commonly used in industries and laboratories to separate dissolved substances from a solution.
