If potassium permanganate is added to a solution and it becomes brown is the substance a reducing agent?

  • $\begingroup$ Permanganate is a strong oxidizier so most substances will be reducing agents in comparison. Even hydrogen peroxide. $\endgroup$ – FrankS Mar 1 at 9:59
  • $\begingroup$ Brown in potassium permanganate reactions usually means you formed MnO2. The cure, If you want a nicer looking reaction forming Mn(II) ion in solution, is to add acid. If you render the balanced equations for permanganate reduction, you find you need a lot of acid to get to Mn(II). $\endgroup$ – Oscar Lanzi Mar 1 at 11:03

Yes, the substance is a reducing agent which will reduce $\ce{KMnO4}$ into $\ce{MnO2 }$ in neutral or weakly basic medium.
