H2C2O4•2H2O(s) + 2NaOH (aq)= Na2C2O4 + 4H2O(l)
part A
Mass of oxalic acid analyzed (g)- trial 1- 0.302 trial 2- 0.305
initial buret reading of NaOH (mL)- trial 1-0.31 trial 2- 23.42
final buret reading of NaOH (mL) trial 1- 23.42 trial 2 -46.73
Part B
volume of vinegar analyzed (mL), trial 1- 5.00 , trial 2- 5.00
initial buret reading of NaOH (mL), trial 1 -0.00, trial 2 - 22.73
final buret reading of NaOH (mL) trial 1- 22.73, trial 2- 45.50
molarity of oxalic acid that was used during the experiment given
