The ionic equation:
2Mn[tex]O^{- }_{4}[/tex] + 5 H2O4 + 6 [tex]H^{+}[/tex]⇄ 2[tex]Mn^{2+}[/tex] + 10 CO2 + 8H2O
Molarity of KMnO4 is 0.0229M
Molarity:
Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of the amount of substance per unit volume of solution.
Formation of the ionic equation:
2 × ( Mn[tex]O^{-}[/tex]4) + 8 [tex]H^{+}[/tex] + 5[tex]e^{-}[/tex] ⇄ [tex]Mn^{2+}[/tex] + 4 H2O )
5 × ( H2C2O4 ⇄ 2CO2 + 2[tex]H^{+}[/tex] + 2[tex]e^{-}[/tex] )
_______________________________________
2Mn[tex]O^{-} _{4}[/tex] + 5 H2C2O4 + 6[tex]H^{+}[/tex] ⇄ 2M[tex]n^{2+}[/tex] + 10 CO2 + 8 H2O
Now we have to find the molarity of the permanganate,
Volume = 28.97ml
mass = 0.1058g
molecular mass = 0.105 × 1000/ 28.97
= 3.62g
molecular mass = 158
Molarity of the solution = mass/ molecular mass
= 3.62/ 158
= 0.0229M
Therefore the ionic equation is 2Mn[tex]O^{- }_{4}[/tex] + 5 H2O4 + 6 [tex]H^{+}[/tex]⇄ 2[tex]Mn^{2+}[/tex] + 10 CO2 + 8H2O and the molarity of the permanganate solution is 0.0229M.
