HELP: In this lab, it is not necessary to calibrate the volume of a drop from a Beral pipet, so long as you use the same Beral pipet for all titrations and you handle it consistently. A solution that contains 3.0 x 10^-5 mol of oxalic acid requires 24 drops of permanganate ion solution to reach the endpoint of the titration. What is the chemical amount of permanganate ion per drop?
Calculate the pH during the titration of 40.00 ml of 0.1000M NaOH Solution after the following additions of base a) 24.00 ml b)39.80 ml c)52.00 ml
