I was asked to predict the product of the reaction between iron metal and chlorine gas: $$\ce{Fe +Cl2->} ?$$ The product here is supposed to be $\ce{FeCl3}$. Could anyone help me with th Then low­er the rod into the green­ish gas, and ob­serve an im­me­di­ate vi­o­lent re­ac­tion: the chlo­rine ox­i­dizes the iron to a triva­lent state. chlorine and oxygen c.) cesium and iodine d.) carbon and chlorine e.) fluorine and iodine. Iron reacts with oxygen, O 2, forming Fe(II) and Fe(III) oxides. The glow of the iron as it was plunged into chlorine is the effect of the vigorous chemical reaction occuring. From this information, the overall reaction can be obtained. The reaction with iron (III) chloride solution Iron (III) chloride is sometimes known as ferric chloride. \ce{Fe^2+ &-> Fe^3+ + e-}\tag{C}\\ A and D cannot be the answer. Part of NCSSM CORE collection: This video shows the reaction of steel wool with chlorine gas. Since it is getting reduced, it is gaining electrons and therefore its oxidation state should decrease after the reaction. Iron(III) halides (FeX3) are formed as coloured solids. Curriculum links include: group 7, reactions of metals, reactivity, trends in group 7, periodicity. Finely divided iron, e.g. sodium magnesium aluminium silicon phosphorus sulfur chlorine argon Answer the following questions using only these elements. Could all participants of the recent Capitol invasion be charged over the death of Officer Brian D. Sicknick? In what way and in what form does iron react with water? \end{align}. Ceramic resonator changes and maintains frequency when touched. As an oxidizing agent, chlorine reacts with a wide variety of compounds, in particular those that are considered reducing agents (hydrogen sulfide [H 2S], manganese(II), iron(II), sulfite [SO 3 2–], Br–, Table 1. This means that procedures reflect general practice and standards applicable at the time resources were produced and cannot be assumed to be acceptable today. copper and tin b.) It only takes a minute to sign up. To learn more, see our tips on writing great answers. This is characteristic of iron(III) ions in aqueous solution.
