Weigh correctly on the watch glass 3.15 g of oxalic acid and record this weight in the notebook. Still have questions? This is the amount of base needed to hydrolyze a certain amount of fat to produce the free fatty acids that are an essential part of the final product. © 2003-2020 Chegg Inc. All rights reserved. Remove the air gap if any, from the burette by running the solution forcefully from the burette nozzle and note the initial reading. Since the question contains multiple parts, the first part is solved. b)How many moles of NaOH(aq) were needed to neutralize the oxalic In acid base titration at the end point the amount of acid becomes chemically equivalent to the amount of base present. NaOH only release one OH- for each molecule dissolved, so you need twice as much NaOH as oxalic acid.
