No, separation of sugar from tea cannot be done using filtration. Filtration is a method used to separate insoluble solids from liquids. However, when sugar is added to tea, it dissolves completely, forming a homogeneous solution. This means that the sugar molecules are dispersed uniformly at the molecular level and cannot be separated by a simple filter.
Why Filtration Doesn’t Work for Sugar in Tea
| Property | Tea + Sugar Solution | Filtration Suitability |
| Type of mixture | Homogeneous (uniform composition) | ❌ Not suitable |
| Solubility of sugar in tea | Soluble – forms a solution | ❌ Cannot be filtered |
| Nature of sugar in tea | Dissolved, not suspended | ❌ No solid particles |
| Example where filtration works | Sand in water (insoluble solid) | ✅ Yes |
Suitable Methods to Separate Sugar from Tea
While filtration doesn’t work, here are some methods that can separate sugar from tea:
| Separation Method | How It Works | Practicality |
| Evaporation | Boil the tea to evaporate the water, leaving sugar (and other solids) behind | Time-consuming, partial |
| Distillation | Boil the tea and condense the vapor to get water; sugar remains in the residue | Effective, but complex |
| Reverse Osmosis | Uses a membrane to separate dissolved substances | Industrial scale only |
| Crystallization (partial) | Cool a highly concentrated solution to crystallize sugar | Only works with high sugar levels |
