Question
1. Consider the balanced ionic equation for the reaction in today's exercise: 5C,042, + 16 H + + 2MnO4 10CO2 + 2Mn2+ + 8H20 The MnO4 salt used is KMn0, the oxalate salt is Na C04 and the acid is H SO4 The Mn. K and Na" all react to form three different sulfate salts. Based on these facts, write the balanced molecular equation for the reaction. 2. Why is it not necessary to know accurately the volume of H SO4 used in the reaction but is necessary to accurately know the volumes of KMnO4 and Na C204 solutions?Explanation / Answer
Balanced molecular equation
5Na2C2O4 + 8H2SO4 + 2KMnO4 = 10CO2 + 2MnSO4 + Na2SO4 + K2SO4
Q2
most likely because H2SO4 is the limiting reactant
so the study is done on this species, since it will end up / react all first
