When a powdered drink mix was added to water, the liquid turned orange. A student decided the taste was too strong, so he poured out half of the liquid and added more water. Which of the following most likely occurred when more water was added?

• The physical state changed
• The orange color became lighter

A student made a mixture using equal amounts of salt and pepper. The salt grains were the same as the pepper grains. What should the student do to most easily separate the pepper from the salt?

• Use a pair of tweezers to remove each grain of pepper
• Run a small magnet through the mixture to attract the pepper
• Put the mixture in water and filter the pepper out of the water
• Use a strainer with a fine wire screen to remove the pepper

Students conduct and investigation to determine which substances are soluble in water.  All of the following have the property of solubility in water EXCEPT -
