The endpoint in the titration is "overshot" A. is the reported molar concentration of the hydrochloric acid solution too high or too low. B. As a result of this poor titration technique, is the reported number of moles of B4O5(OH)4^2 would be too high or too low?
Calculate the number of moles of Ascobic acid in the 50.00 ml Sample. Titration Volumes of KIO3 Initial Buret reading/ml trial 1=12.54 trial 2=8.78 Final buret reading/ trial 1=38.74 trial 2=34.93 Volume of KIO used/ml trial 1=? trial 2=?
