Potassium, sodium, lithium and calcium all react violently with dilute sulfuric acid and dilute hydrochloric acid. Iron converts to sparingly soluble and amorphous ferric tannate complexes. Rust is actually a mixture of different oxides of iron, but the Fe 2 O 3 of our earlier example is an important part of that. The reaction between tannic acid and metallic iron was studied using infrared and Mössbauer spectroscopy. Binding constants between iron(II1) and 21]. There was no evidence of electron transfer occurring in the complex formed when iron (III) is reacted with naringin. Iron carbonate has a water solubility of 60 mg/L, iron sulphide of 6 mg/L, and iron vitriol even of 295 g/L. You can ob­serve it by adding acid to iron. Rust gives off an unwanted taste to water and other liquids. Over-the-counter solutions of citric acid are generally offered at low concentrations, so they are more safe. When an HCl solution is added to iron powder, the H+ and Cl- ions from hydrochloric acid disassociate.
