You were asked to determine the acid content of vinegar and soda samples. You performed a simple acid-base titration using a solution of NaOH as the titrant with phenolphthalein as the indicator. To determine the concentration of the NaOH solution, you first performed standardization using KHP (FW: 204.22 g/mol, 99.94% purity). For analyzing the samples, he separately measured a volume of vinegar and soda then transferred them to a flask. Complete the table using the provided data. a) Standardization of NaOH Solution Trial 1 0.1012 0.00 4.95 Weight of KHP, g Initial volume of NaOH, mL Final volume of NaOH, mL Molarity of NaOH Average Molarity of NaOH Trial 2 0.1004 5.00 9.99 Trial 3 0.09987 10.01 14.93
