Mn2+ (aq) + 2OH-(aq) >>> Mn(OH)2 (solid, pale pink)
Mn2+(aq) + C2O4 2- (aq) >>>> MnC2O4 (solid, pale pink)
2Mn2+(aq) + [Fe(CN)6]4- >>> Mn2Fe(CN)6 (solid, pale green)
2Mn2+(aq) + 5BiO3-(aq) + 14H+ (aq) >>> 2MnO4-(aq, deep purple) + 5Bi3+ + 7H2O (l)
Can someone please point me in the right direction? I believe it is the fourth one because the MnO4 compound is aqueous and there is liquid water involved.
Thank you.
