Question
how do you calculate the number of miles KMnO4 used? This was a dry lab.
Read the experiment in the lab manual including the procedure and appendices. Pass in the completed pre-lab. Do the following: Trial A Trial B Trial C 1.83 mL 0.91 mL Initial Buret Reading (mL) 0.23 mL Final Buret Reading (mL) 26.48 mL Volume of KMno, used (L) 002025L # moles KMnO4 used # moles of oxalate in diluted solution 28.67 mL 27.49 mL Molarity of dilute solution Molarity of Concentrated Oxalate solution AVERAGE MOLARITY OF CONCENTRATED OXALATE SOLUTION Write equations for: A. The two half-reactions B. The balanced redox equation Display the calculation and reasoning for Trial A only. Show the calculation for the average value for the molarity. Use he reverse side.Explanation / Answer
we know,
moles = volume in L * molarity.
from final and initial burette reading, we can calculate the volume of KMnO4 used in each trial.
But we need the molarity of KMnO4 stock solution which is used in buratte.
you must be known the molarity because in burate we use a known concentration solution.
so using formula we can calculate the moles of KMnO4.
moles of KMnO4 = volume of KMnO4 used in L * molarity of KMnO4 solution.
