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?

Question

A. Boil the water away, leaving the substance behind in the beaker.
B. Pass the solution through a filter to let the dissolved substance separate.
C. Use a magnet to draw out the solid substance from the water.
D. Pour the liquid along a rough surface that would catch the solid particles but not the water.

Answer 1

To separate a solid substance that has dissolved in water, the correct method would be:

A. Boil the water away, leaving the substance behind in the beaker.

When a solid dissolves in water, it forms a solution, and boiling the water will cause it to evaporate, leaving the dissolved substance behind if it's a non-volatile solid. The other options are not suitable for separating a dissolved solid from a liquid.
