During science class, while studying mixtures, you mix together table salt and sand. Your teacher challenges you to separate the salt from the sand. What property could you use and how would you use it?

• solubility; Add water to the mixture solubility; Add water to the mixture and dissolve the salt. and dissolve the salt.

• particle size; Pour the mixture through a paper filter to separate the two.

• color; Pick out one of the two solids by using color to guide you.

• density; The two will form two layers. Scoop out the top layer.

Carol accidentally dropped a container of salt, sodium chloride into a container of a dark gray metal. Carol knows that the salt will dissolve in water, but she is afraid to pour water over the mixture. On a hunch, she takes a magnet and runs it through the mixture. The gray substance is attracted to the magnet and she is able to separate the two solids. What is the gray substance in the container?

• sodium chloride

• copper

• iron

• aluminum
