The next seven questions explore the effect of errors occurring during experimental titrations on the the final answer. Sometimes the error skews the calculation and returns an answer that is too high or too low. Sometimes an error has no effect and sometimes it makes completing the calculation impossible. Decide what would happen in each case. A student forgets to fill the buret tip with NaOH before beginning the titration. What effect does this have on the calculated concentration of acetic acid in the vinegar
