Web21 sep. 2024 · Common Methods for Making Iodine. Iodine is formed by adding bromine liquid to an aqueous solution of potassium iodide or passing chlorine gas. 2KI + Br 2 → 2KBr + I 2. 2KI + Cl 2 → 2KCl + I 2. Adding potassium iodide to copper sulfate solution also forms iodine. 2CuSO 4 + 4KI → Cu 2 I 2 + 2K 2 SO 4 + I 2. Web1 dag geleden · Chlorine. If you pass chlorine gas over hot iron, the iron burns to form iron(III) chloride. Iron(III) chloride forms black crystals if it is anhydrous. Any trace of water present in the apparatus, or in the chlorine, reacts with this to give reddish-brown colours. 2Fe + 3Cl 2 2FeCl 3. The iron has been oxidised from an oxidation state of zero ...

WebProperties of the Halogens. Fluorine is a pale yellow gas, chlorine is a greenish-yellow gas, bromine is a deep reddish-brown liquid, and iodine is a grayish-black crystalline solid. Liquid bromine has a high vapor pressure, and the reddish vapor is readily visible in [link]. Iodine crystals have a noticeable vapor pressure. WebChlorine can undergo addition or substitution reactions with organic compounds. Chlorine displaces the heavier, less electronegative halogens, bromine and iodine, from … WebScience Chemistry Methane gas (CH4) reacts with chlorine gas (Cl2) to produce liquid carbon tetrachloride (CCl4) and hydrogen chloride gas (HCl). The balanced chemical equation for the reaction is as follows: CH4 (g) + 4 Cl2 (g) → CCl4 (l) + 4 HCl (g). Calculate the number and types of atoms present in the reactants in this chemical equation. duty-free store
