After a polarization test of a carbon steel sample in a bicarbonate solution, can I do a second test with a different sample in the same solution?

11 November 2013 1 7K Report

Does the chemical composition of bicarbonate solutions change so significantly after a polarization test that I can not do another test in it?

Dave Loveday

Dear Faisal

It depends how much polarization you performed. Ideally you would use fresh solution every time especially if you are going to publish your data. If you find something interesting you will always have a doubt about what caused it.

Best regards

David
