Since experiment no. 1 is not given I am solving 2
SOLN 2
moles of Na2C2O4 = molarity * volume = 0.02557*0.1468 = 0.003753 moles
(1L=1000 mL)
From the Balanced equation we know that 2 moles of KMnO4 will require 5 moles of Na2C2O4
hence moles of KMnO4 required = (2/5) * 0.003753 = 0.001501 moles
Molarity = moles / volume in L
M = 0.001501 / 0.03545 = 0.0423 M
PLEASE LEAVE THE POSITIVE FEEDBACK IF YOU LIKE THE SOLUTION

Introduction Titration is a common analytical technique that is used to verify the concentrations of chemicals before they are sold as commercial products, in a process known as quality control. In this lab, you will be using a redox titration to find the concentration of the strong oxidizing agent hypochlorite (CIO) which is the active ingredient in bleach. Oxidizing and reducing agents are often determined using a redox titration....
