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.
