Question

Cuantos KMnO4 se necesita para oxidar 100g de Na2C2O4 vea la siguiente reaccion: NaC2O4 + KMnO4 + H2SO4 = K2SO4 + Na2SO4 +MnSO4 + CO2 + H2O

Answer 1

10 NaC2O4 +2KMnO4 +8H2SO4 → K2SO4+5Na2SO4+2MnSO4 +20CO2 + 8H2O

Mm KMnO4 = 158 g/mol

Na2C2O4 = 134 g/mol

gKMnO4= 100 g Na2C2O4 x 1 mol Na2C2O4 x 2 mol KMnO4 x 158 g KMnO4

134 g Na2C2O4 10 mol Na2C2O4 1 mol KMnO4

g KMnO4 = 23.58
