Question

1. explain how to separate the sugar and water in a solution of sugar and water.
2. how would you separate a mixture of alcohol and water?
3. how would you separate sand and water?

Explanation:

Step1: Separate sugar - water solution

Evaporate the water. Heat the sugar - water solution. Water will turn into vapor and leave behind the sugar crystals.

Step2: Separate alcohol - water mixture

Use distillation. Alcohol has a lower boiling point than water. Heat the mixture. Alcohol will vaporize first, be condensed and collected separately.

Step3: Separate sand - water mixture

Use filtration. Pour the sand - water mixture through a filter paper in a funnel. Sand will be retained on the filter paper while water will pass through.

Answer:

1. Evaporate the water to get sugar crystals.
2. Use distillation to separate alcohol and water.
3. Use filtration to separate sand and water.
