How will the following situations affect the final calculation of the molarity of acetic acid? An air bubble was present in the tip of the buret when making the initial volume reading, but not when making the final volume reading.  A small amount of vinegar adhering to the side of the flask was left unreacted when the end point was thought to have been reached.  The endpoint of the vinegar titration was surpassed (excess NaOH was added) After rinsing any drops of vinegar adhering to the side of the flask, another 20 mL of deionized water was added to the vinegar in the flask After the standardization of the NaOH solution using solid H2C2O4 * 2H2O, the molar mass of anhydrous oxalic acid was used to calculate the molarity of the NaOH solution.
