Hi, it was actually an observasion that we had on our carbon steel pipe we use. so i was looking for an explanation?, anyhow what could be the effect of concentration of acid on pitting corrosion. are they directly propotional?
thanks for replying, i just wanted a general explanation. maybe at 10 % HCL concentartion the hydraogen ion at the cathode would form a barrier that might inhibit corrosion. can this be possible?
