Abstract
The synergistic effects of some ions such as KI, KCl and KBr on the corrosion inhibition of
zinc in 0.4 M HCl by tetrahydrocarbazole derivatives compounds has been investigated
using weight loss measurements. Potentiodynamic anodic polarization technique was used
to measure the pitting corrosion potential and Quantum Chemical studies (Computational
Study) were investigated. Results obtained show that these compounds are good inhibitors
and their inhibition efficiencies (IE%) increase with the increase of inhibitor concentration. ..
