Question
Consider the following hypothetical scenarios and propose how they
may impact
(a) the components of a calibration curve (axis values, slope, R-
squared value, y-intercept and
(b) the precision and accuracy of your calculated unknown
concentration.
Scenario 1: Your pod took replicate measurements that had large standard
deviations.
Scenario 2: The cuvette you used was improperly cleaned, and there was
already trace amounts of copper sulfate solution in the cuvette. All other
techniques were done properly.
Scenario 3: Your pod did not read the meniscus at eye level, instead
choosing to read it while standing up and looking down at the volumetric
flask
