Homework Help: Acidicity of KMnO4

  1. Apr 29, 2008 #1
    How could I estimate the pH of KMnO4 solution (strong oxidizer)? I believe it is neutral, but is that because it takes part in redox reactions and not acid/base or another reason?

    Hint: it is a salt of a strong base and strong acid (HMnO4).

    Do you have the Ka value for Permanganic Acid? I'm about 500 miles removed from my CRC. Permanganic acid and the MnO4- salts are not on any of my reference materials as being a strong/weak anything. I do know that MnO4- is a great oxidizer though.

    pKa = -0.3 (for ionic strength 1.0).

    it's a highly oxidized salt
