Elodia is investigating the physical and chemical properties of calcium hypochlorite (powdered bleach). Her lab report must describe its acidity, color, density, magnetism, and solubility in water. She has only a very small amount of calcium hypochlorite, so she must re-use it for each step of the investigation, and she has only 15 minutes to complete the investigation. She can use a balance, a beaker, a graduated cylinder, a magnet, pH testing liquid, and water.
