Final answer:
The question lacks specific details required to provide an accurate answer on the volume of air to be placed into the blue pigtail using an Asepto syringe. Without such information, it's imprudent to suggest any particular volume.
Step-by-step explanation:
The question does not provide enough specific information to determine the exact volume of air to be placed into the blue pigtail using an Asepto syringe. Typically, the amount of air or liquid to be pipetted would be specified in a laboratory protocol or experiment instructions. Since the question references pipette practice and aseptic techniques, it is important to note that precise measurements are crucial in many biological experiments, particularly those involving the transfer of sterile liquids. The context described in the question involves practicing aseptic techniques by using a graduated pipette to draw up and release water in 1 ml increments up to 5 ml total. This is important for ensuring that contamination of sterile substances is minimized in a laboratory setting. However, without clear instructions to reference, suggesting an answer would be inappropriate, as it may lead to inaccurate conclusions in the student's work.
