Volumetric pipettes are designed to deliver a very precise amount of liquid, but only if you O a. submerge the end of the pipette into the solution you are delivering. O b. allow the pipette to drain freely, and leave any residual solution in the pipette. Oc use the bulb to blow out any residual liquid left in the pipette. O d. hold the pipette at a 45 degree angle and ensure that all the liquid is delivered.

Step 1
Volumetric pipette is used to measure exact amount of a solution. Volumetric pipettes are always calibrated in such a way that these pipettes deliver accurate amount of volume of solution. The aim of calibration of volumetric pipette is to minimize the uncertainty or any errors in the accuracy of volume of the solution.
