Question

Suppose you had started with an air bubble in your buret tip during one replicate of your practice titration experiments, but by the time you reach the endpoint it was gone. How will this affect your accuracy and precision in determining the concentration of your unknown? Be specific.

Answer 1

If we start one of our trial tritration with a bubble inside the burette which is gone at the end of the titration, then the reading that we will get for this trial will be a little more than the actual value that we should get or that we got during the other trials. Hence this difference in values will affect the accuracy of our final result as their we are supposed to take the mean of all the values we get. And this will result in high precision of the final result . Because accuracy means how close are we to the actual result (less decimal places) and precision means how much precise the values are ( more decimal places).
