The present work highlights the corrosion inhibition action of two indole-3-hydrazides with varying alkyl chain lengths: 2-(1 H -indol-3-yl)acetohydrazide (IAH) and 4-(1 H -indol-3-yl)butanehydrazide (IBH) against mild steel (MS) in 0.5 M hydrochloric acid (HCl) solution using electrochemical and gr...
