In this experiment you were given the concentration of NaOH(aq). That concentration was determined in part A.1. by using a solid acid, potassium hydrogen phthalate. Suppose the potassium hydrogen phthalate used for the standardization of the sodium hydroxide solution is not completely dry. This technique error will result in the reported concentration of NaOH(aq) to be ____________. a. unaffected b. too high c. too low
00 mL of a diprotic acid primary standard solution was accurately prepared to a concentration of 0.1431 M. Three samples of this primary standard solution were used as samples in a titration to standardize an aqueous solution of sodium hydroxide, NaOH, which would be used as a titrant. Using the following table of data for the titration of the primary standard acid with NaOH, calculate the average concentration of NaOH.
