Between 100% pure liquid hydrochloric acid at p=80 bar and 38% hydrochloric acid also at p=80 bar which is more corrosive?

12 December 2018 1 5K Report

does presence of water in 38% acid makes any differences?

temperature is the same.

38% water containing hydrochloric acid will be more corrosive as the presence of water makes faster to react with metals by acid.
