salt is not soluble in alcohol while sugar is, salt will settle at the bottom. can we separate by filtration?

Yes, you can separate salt and sugar mixed in alcohol by filtration. Here's how:

1. Pour the mixture into a filter paper set in a funnel.
2. The alcohol and dissolved sugar will pass through the filter paper, while the insoluble salt will remain on the filter paper.
3. Collect the filtrate (the liquid that has passed through the filter paper). This contains the alcohol and sugar.
4. To separate the sugar from the alcohol, you can use evaporation or distillation. Heat the filtrate gently. The alcohol will evaporate first as it has a lower boiling point than sugar. The sugar will be left behind.
5. The salt can be collected from the filter paper once it's dry.

Remember to perform this under the supervision of an adult or a science teacher, as it involves the use of heat and alcohol.
