As the lab was taking place, is it possible that the atmospheric (air) pressure may have changed? If it did change, how could the results have been affected? What
other variables may not have been accounted for in this lab?
(Hint: Air pressure changes if a weather front is moving through the area, such as
might be the case when rainstorms occur.)

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
