2. Would the calculated value of the molarity of the NaOH solution be too high or too low or unchanged if the following errors were made? Explain your answers. a) the beaker into which the student poured the NaOH solution from the fume hood had some distilled water in it b) the flask into which the student weighed the KHP was wet c) the buret tip was too far above the mouth of the flask and two drops of the NaOH ran down the outside of the flask d) an air bubble was in the tip of the buret when the student started the titration
