Title: Trying to workout iCorr
Post by: dscot on May 04, 2013, 02:40:33 PM

Hi all,

I'm currently trying to do this question: http://screencast.com/t/oVPjqkLk6KvP

It seems pretty simple

• Workout equilibrium potential
• Use the mass transport limiting current as the corrosion current
• work out corrosion potential
• repeat - this time diving the corrosion current by 250

My question is why was the original O2 concentration included? It makes me feel like I'm missing something out of the calculation?
