Obtain egg albumin or make the egg albumin solution by mixing the white from one egg with 200 ml of water Filter this through cheesecloth into a beaker. 2. Obtain five test tubes and a rack. Label the tubes 1 to 5. 3. Add -2.5 mL of the egg albumin solution to each tube. 4. Perform the tests as described below. Record your observations of the egg albumin solution before and after each test Heat: Hold test tube #1 with a test tube holder and heat the solution gently over a low flame Acid: Add 2 ml. of 10% HNO, to test tube #2 and shake gently Base: Add 2 ml. of 10% NaOH to test tube #3 and shake gently • Alcohol: Add 4 ml of 95% ethanol to test tube # 4 and shake gently Heavy metal ions: Add 20 drops of 1% AgNo, to test tube #5 and shake gently Virtual Observations: The albumin solution is slightly off-white and cloudy, with some bubbles at the surface Describe the initial appearance of the egg albumin solution Normal BIU 1
