The corrosion of metals and their alloys has prompted increased research efforts to lessen the harm caused by the corrosion process. The study analyses the ability of Kair (Capparis decidua) shrub extract to suppress corrosion on metal in 0.1 N HCl and 0.1 N H2SO4 solutions using thermometric and weight loss techniques. At all extract concentrations, it was shown that the shrub extract efficiently prevents zinc corrosion. The inhibitory action is determined by the concentration of the shrub extract in the acidic solution. The findings of mass loss measurements indicate that inhibition efficiency increases with inhibitor concentration. Based on thermodynamic considerations, the extract's adsorption is exothermic and spontaneous. From the results and findings of the study, a physical adsorption mechanism is proposed for the adsorption of ethanol extract of Kair shrubs extract on zinc surface. The inhibitory efficiency was projected using certain methods at 303K, 313K, and 323K temperatures. As the extract's concentration rose, the inhibition effectiveness rose as well, demonstrating the shrub extract's inhibitory ability. The extrapolation of enthalpy, entropy change, activation energy, and Gibbs free energy provided evidence for this. The thermodynamic variable demonstrates that physisorption was the mechanism of inhibition. Therefore, the current research shows a new, ecologically safe, and effective corrosion inhibitor for protecting zinc surfaces in acidic environments.
