Suppose a 1.0mL air bubble is trapped in the tip of your buret and you don’t notice it before measuring out liquid samples with the buret. What percentage error would be introduced in a 35.0mL sample of liquid if the air bubble comes out of the tip of the buret while the liquid sample is being transferred?Hint: % Error=observed- acceptedaccepted×100

Pipets used for the transfer of samples of solutions are always rinsed with a small portion of the solution to be dispensed with the pipet before the actual sample is taken. Calculate the percentage error likely to arise in an experiment if a 10mL pipet is used for transfer and contains 5 drops of liquid adhering to the inside of the barrel. Assume a volume of about 0.05 mL per drop. Hint: % E r r o r = o b s e r v e d – a c c e p t e d a c c e p t e d × 100 Answer: [BLANK-1]% error
