1. The problem statement, all variables and given/known data

Given a 0.1 M solution of Ba(MnO4)2

2. Relevant equations

What is the Normality if it is used as an oxidizing agent in strong acid (Mn2+ formed)?

What is the Normality if it is used as an oxidizing agent in a weak acid (MnO2 formed)?

Define strong and weak in terms of pH.

3. The attempt at a solution

(0.1)(10 moles electrons total/2 mole) = 1 N
(0.1)(6 moles electrons total/2 moles) = 0.6 N
Schaum's Outline gets 0.5 N and 0.3 N respectively. I'm just curious about the weaky/strong acid thing myself. What's the cutoff pH?
