Compare the pKa1 and pKa2 values you determined experimentally with the literature values of your text book (you will need to convert the text book Ka values to pKa’s). Calculate the percent differences between your experimentally determined values and the literature values (make sure you use the proper formula for calculating ""percent difference"").

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
