Can superabsorbent polymer crystals absorb any other liquids besides water?
In this experiment, determine if this crystal can absorb other liquids by adding them to orange juice, vegetable oil, milk, rubbing alcohol, vinegar, and club soda.
A hydrogel crystal (sometimes called a "disappearing crystal," "water crystal," or "superabsorbent gel,") is a long chain of molecules bonded together to form a superabsorbent polymer that does not dissolve, but forms a gel when placed in water. It is often used in gardening, landscaping, and farming as a way of retaining moisture. The crystal is made up almost entirely of water. As the crystals dry, water is slowly released to the soil. Some of these crystals can soak up as much as 500 times their weight in water! This superabsorbent characteristic makes hydrogel crystals useful in solving water conservation issues.
