Question
Part B. Directions: oot M solution ofpotassium permanganate 1 Prepare exactly 50 mL ofa from a stock solution of 0.00250M KMnO solution was prepared including all equipment/glassware utilized as well as the steps that were followed. Show all work for your calculations and write a detailed explanation on how the Calculations/Explanation: After your assigned solution is prepared, measure the absorbance on a spectrophotometer at 540 nm. Be sure to use deionized water as the reference/blank. Explain the procedure that you followed for taking the absorbance measurement. 2. @ 540 nm Absorbance:_
Explanation / Answer
from dilution formula
M1V1 = M2V2
M1 = molarity of KMnO4 STANDARD = 0.0025 M
V1 = volume of KMnO4 standard must take = x ml
M2 = molarity of KMnO4 diluted = 0.001 M
v2 = volume of KMnO4 diluted = 50 ml
0.0025*x = 0.001*50
x = 20 ml
take 20 ml of standard KMno4 solution and add water upto 50 ml.so that, you will get desired solution.
