The Mn_3O_4formed on strong heating of a sample of MnSO_4 . 4H_2Owas d – InterviewSolution

1.	The Mn_3O_4formed on strong heating of a sample of MnSO_4 . 4H_2Owas dissolvedin 100 cm of 0.1 N FeSO_4containing dilute H_2SO_4 . The resulting solution reacted completely with 50 cm^3of KMnO_4solution. 25 cm^3of this KMnO_4solution required 30 cm^3of 0.1 N FeSO_4solution for complete reaction. Calculate the amount of MnSO_4 . 4H_2Oin the sample.
