Using Excel, calculate a titration curve for a weak acid with a pKa of 3.57 with a
standardized NaOH solution of 0.1138 M. This curve should have a minimum of 20
calculated points; 15 before equivalence, equivalence, and 4 after equivalence. It is
STRONGLY recommended that you use the referencing features within excel to perform
these calculations. They may be done by hand, but will be extremely tedious! Submit
your (printed) results with an appropriately labeled figure and ALL calculations shown in
the immediately adjacent cell.

Formal concentration is 0.1000 M

Assume a 25.00 mL aliquot

Please show all work and the formulas you typed into excel
