You are worried that a solid substance has dissolved in a beaker of water in a lab. What would be a way to separate the substance from the water?

Answer 1

One possible way to separate the substance from the water is through the process of evaporation.

1. Start by heating the beaker with the mixture of water and solid substance.
2. The heat will cause the water to evaporate and turn into vapor, leaving behind the solid substance in the beaker.
3. Make sure to collect and condense the water vapor to retrieve the pure water.
4. Once all the water has evaporated, you can safely collect the solid substance left in the beaker.

Please note that this method is applicable if the solid substance has a significantly higher boiling point than water. If the solid substance has a similar or lower boiling point, other separation techniques such as filtration, chromatography, or distillation may be required.
