III.50 mL BuretObtain a clean 100 mL volumetric flask and use the analytical balance to weigh it to the nearest 0.0001g. Assemble the buret apparatus by mounting the buret onto a buret stand and fill the buret with distilled water. Ensure that the buret is vertical, the buret tip is filled, and that there are no air bubbles within the stopcock. Place the 100 mL volumetric flask underneath the buret tip and open the stopcock to allow the meniscus to descend a few millimeters. Then open the stopcock again and allow ~10 mL of water to flow into the flask. Record how much milliliters were released to the nearest 0.01 mL. Weigh the receiver and water on the analytical balance. There is no need to empty the receiver for the next trials. Continue to add another ~10 mL portion of water, record how much milliliters were released to the nearest 0.01 mL and weigh again. Add a third portion of ~10 mL portion of water, record the mL and weigh the receiver and water again.
