Question

During a titration a student uses the pipette bulb to force out the final drop of the basic solution from the payback how will this mistake affect the calculated concentration of the basic solution

Answer 1

Answer:

we are never supposed to blow out excess solution from the pipet. Pipets are calibrated to deliver the appropriate amount of solution. If we are trying to deliver 5mL of solution and blow the extra amount out, it will exceed 5mL. This would result in an inaccurate high determination.
