Properties and Changes Logan Bell Purpose: The Purpose of the Properties and Changes lab was to determine the unknown substances in the assigned mixture by comparing reactions and end results with certain variables. Procedure: Part one: 1. Obtain one of the following white powders: Starch, Baking Soda, Sugar and Salt (Sodium Iodide) 2. Make as many observations of each powder that you can before it is mixed with anything. Record your observations in your data table. 3. Put a small amount of your Sugar in two pea sized piles on a watch glass. 4. Add one drop of Vinegar to one of the piles of Starch. Record your observations. 5. Add one drop of Iodide solution to the other pile of Starch. Record your observations.
