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. STANDARDIZATION OF NAOH SOLUTION TRIAL 1 0.1012 TRIAL 2 TRIAL 3 Weight of KHP, g Initial volume of NaOH, mL Final volume of N2OH, mL 0.1004 0.09987 0.00 5.00 10.01 4.95 9.99 14.93 Molarity of NaOH Average Molarity of NaOH
