Copper changes colors

Nathan Wright, junior kinesiology major, uses a pipette to introduce ammonia into a copper filled test tube in Professor of Chemistry Mark Nelson’s Chemistry 202 lab May 11. The solution formed a metal amino ion, causing the liquid to change color. The purpose of the experiment was to see if adding different chemicals to change the temperature of metal solutions affects their pH levels. / photo by Cortney Mace
