Question
olid oxalic A sample of oxalic acid is prepared by weighing an empty Erlenmeyer flask, adding s acid to the flask, measuring this combined mass, and then determining the mass or ok 3 pr by difference. 1. 135.728 g 137.178 g NSO Mass of flask Mass of flask and oxalic acid What mass of oxalic acid is present in the flask? 2. During a titration the following final and initial volumes are measured with a burette. Final burette reading Initial burette reading Volume of KMno, delivered 28.41 mL o, 03 8 0.31 mL 0,000 001- What volume of KMnO solution was delivered into the reaction flask? s. 14 o.DJ310L- What volume of solution in liters was delivered into the flask in question 2? Please show your answer and the details of the calculation that you did to get that answer. 3. }.AD., lycSAExplanation / Answer
It is the titration of oxalic acid vs KMnO4.
the overall reactin for the above experiment is
2 KMnO4 + 3 H2SO4 + 5 H2C2O4. 2H2O GIVES RISE TO K2SO4 + 2MnSO4 + 18 H2O + 10 CO2
In the above equation 2 moles of kmno4 reacts with the 5 moles of oxalic cid.
you have to convert simply ml to Litre
1 L= 1000ml
