Question

Как разделить сахар и медь?

Answer 1

1)Добавить в  смесь  воды - медь  осядет, сахар   растворится.
2)Слить  сладкий  раствор - медь  отделили.
3) Сладкий  раствор  поставить  на  огонь  -  вода  выпарится, сахар  останется...

Answer 2

Сахар с песком растворить в воде, процедить через фильтр (например, через марлю в несколько слоёв) Воду выпарить. 
медные и железные опилки можно разделить с помощью магнита (медь не магнитится)

How to Separate Sugar and Copper?

To separate sugar and copper, you can use the differences in their physical and chemical properties. Here's a detailed explanation of the process:

1. Physical Properties: - Sugar and copper have different physical properties that can be utilized for separation. Sugar is a crystalline solid, while copper is a metal with a distinct color and density.

2. Dissolution and Filtration: - One method to separate sugar and copper is by dissolving the sugar in water. Since copper is insoluble in water, it will remain as a solid. After dissolving the sugar, the mixture can be filtered to separate the undissolved copper from the sugar solution.

3. Density-Based Separation: - Another approach is to utilize the difference in density between sugar and copper. Since copper is much denser than sugar, it can be separated from sugar by using techniques such as flotation or centrifugation.

4. Chemical Properties: - Additionally, the chemical properties of copper and sugar can be exploited for separation. For example, copper can be dissolved in acids such as nitric acid, while sugar remains unaffected. This allows for selective dissolution and subsequent separation of the two substances.

5. Conclusion: - In summary, the separation of sugar and copper can be achieved through various methods based on their physical and chemical properties. These methods include dissolution and filtration, density-based separation, and selective dissolution based on their chemical reactivity.

By utilizing these methods, it is possible to effectively separate sugar and copper based on their distinct properties.
