Describe how to use a transfer pipet to deliver 10.00 mL of liquid by placing the following steps in the Map correct order. First step Last step Replace the bulb with your index finger and wipe excess liquid off the outside of the pipet. Place the tip of the pipet against the side of a beaker and drain liquid from the pipet until the bottom of the meniscus reaches the center of the calibration mark Transfer the pipet to the receiving vessel. Drain the pipet by gravity while holding the Scroll down to view tip against the side of the receiving vessel. all of the steps. Use a rubber bulb to suck liquid up past the 10.00 mL calibration mark. Suck up a third volume of liquid past the 10.00 mL calibration mark. Discard the first two pipet volumes of liquid to rinse the pipet. A Previous Check Answer Next Exit 8 HintExplanation / Answer
We can use the pipet by taking a suction device to suck up liquid into pipet. Then we will fill the pipet upto the 10mL marks and will discard the initial two volumes of liquid and will take a final third volume. We will replace the bulb with index finger and will drain it by placing the tip of pipet at the wall of beaker and drain the liquid.
