In this study, the properties of quercetin (3,3′,4′,5,7‐pentahydroxyflavone) solution towards CaCO 3 formation were evaluated by using chronoamperometry (CA) and impedance measurements. Quercetin a flavonoid present in plants as a secondary metabolite. Using CA, precipitation of CaCO 3 was totally inhibited by adding 2 mg/L of quercetin ( T = 30°C). The same result was obtained by impedance measurements. Scanning electron microscopy (SEM) and X‐ray diffraction (XRD) were used to characterize the calcium carbonate scale without or with quercetin treatment. The predominant crystalline structure corresponds to a mixture of calcite and aragonite.
