Your teacher has mixed salt, pepper, and water. What is a procedure that you could use to separate this mixture?

Filter out the pepper, then boil the water to get the salt.


The key concept to realize here is that pepper and salt have different solubilities in water. Salt is soluble, pepper is not. As a result, you can simply filter out the pepper using filter paper.

Once you've done that, all you have to do is evaporate the water, and then you'll be left with the leftover formerly dissolved salt.

Hope that helped :)
