Denaturation of Proteins Use the virtual observations and videos provided to collect data virtually. If you have technical issues with the virtual data, please contact support From the procedure 1. 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
